Remember, it's Not Just a Grid Control! The ExpressQuantumGrid Suite includes the best grid control in the business - so good in fact, in a review by Delphi Informant Magazine it was said of the QuantumGrid, "After my experience with ExpressQuantumGrid and ExpressInspector... I can't imagine developing a Delphi database application without these tools. The grid is the most capable VCL grid I've found. Just by using a small part of its capabilities and customization options, my applications seem more professional, and the users enjoy the editing capabilities." Page 2 of 3406

But... The Suite is far more than this powerful grid control... the suite is also comprised of over 70 standalone field editors and individual controls - many available in data-aware and non data-aware editions. Total Control, Flexibility and Power The Only No Limits Grid and Data Editors Library Available for the VCL

Whats New in v6Know n Issues and Important Changes List

This topic provides a brief overview of the new features introduced in the ExpressQuantumGrid Suite v6. Click a link below to jump to the corresponding section. Data Handling Enhancements Charting Capabilities Card View Features Table View and Banded Table View Features Common Features Design-Time Experience Data Handling Enhancements Filtering UI Innovations:l

l

Filter Row. A specially designed Filter Row allows you to apply a filter condition directly within the grid. Use the Views FilterRow.Visible and FilterRow.ApplyChanges options to activate the Filter Row and specify its filter update mode. Checked Lists in Column Filter Dropdowns. Column filter dropdowns now use checked lists. Use the View's Filtering.ColumnPopup.MultiSelect and Filtering.ColumnPopup.ApplyMultiSelectChanges options to activate checked lists and specify their filter update mode. A grid items Options.FilteringPopupMultiSelect property allows you to control the appearance of a checked list for individual columns and card rows. Synchronized Filter Dropdowns. Filter dropdowns can now be populated only with currently available items (that have not been filtered out). To enable this feature for an entire View, use the Views Filtering.RowFilteredItemsList and Filtering.ColumnFilteredItemsList properties. To enable this feature for individual columns and card rows, use a grid items Options.FilteringFilteredItemsList property.

Improved Date/Time Value Handling:l

More flexible filtering capabilities: You can set the Views DateTimeHandling.IgnoreTimeForFiltering property to True to force the View to ignore the time portion of date/time values. This means that filter dropdowns will be populated with dates without their corresponding time element. In either case, the time element is taken into consideration when you sort data. Time intervals and time ranges relative to the current date (such as a year, month, previous week, etc.) in filter dropdowns displayed for date/time columns. The availability of these advanced filter items is controlled by the View's DateTimeHandling.Filters property. You can extend the built-in collection of date ranges with your own, by handling the OnInitFilteringDateRanges events for a View and an item.

l

More flexible grouping capabilities: The Views DateTimeHandling.Grouping property allows you to specify how date/time values should be combined into groups. You can specify grouping options for each column, using the columns DateTimeGrouping property. Similar to the filtering capabilities, the most frequently needed group types are built-in. You can easily add custom grouping types by handling a specially designed OnInitGroupingDateRanges event for a View and a column. As with filter conditions, group types are represented by the same date range classes. Once created, a custom date range can be used both to filter and group data.

l

Customizable formats for dates in filter dropdowns and group rows (via the Views DateTimeHandling sub-properties).

Charting CapabilitiesPage 4 of 3406

l

l

l

l

l

Three New Chart Types: Line, Pie, and Area Charts. Use the Views DiagramLine, DiagramPie, and DiagramArea properties to access their appearance settings. Data Mining Using Data Groups and Drill Down. This feature has much in common with group summaries in Table Views. You can specify a field whose values will be used to group data. The chart will display values calculated against each group instead of each individual value. Refer to the Creating Data Groups in Chart Views topic, to learn about this feature. End-User Chart Customization Capabilities. A new UI element a Toolbox allows straightforward end-user chart customization by means of the following tools: data level navigator, chart customization button, and diagram type selector. Use the Views ToolBox property to control the general appearance of the Toolbox. Paging Category Scrolling. You can specify the maximum number of categories simultaneously displayed in a chart, via the Views OptionsView.CategoriesPerPage property. Customizable Value Axis Display Range. You can restrict the display range of value axes based upon plotted chart values, and also provide arbitrary upper/lower axis limits (via the diagrams AxisValue.MinMaxValues, AxisValue.MinValue, and AxisValue.MaxValue properties).

Card View Featuresl

l

l

l

l

l

Expandable Category Rows. To create a category, add a new row and set its Kind property to rkCategory. Data rows that follow a category automatically become its children. If there is another category row, it starts its own new category, etc. Collapsing a category within a card affects all cards. This allows end-users to hide unnecessary fields with just a single click. More Flexible Row Layout. You can use the Views RowLayout property to specify whether rows should be arranged vertically, one under another, or horizontally from left to right. At design time, you can create whatever layout you need by simply dragging rows to their desired position. And you can allow end-users to do the same. For this purpose, enable the Views OptionsCustomize.RowMoving and OptionsCustomize.LayeredRows properties. Automatic Card Width Adjustment. If the Views OptionsView.CardAutoWidth option is enabled, cards are automatically resized to fit into the View. So, you can resize the View to display more or less cards. Show Hidden Empty Fields While Editing. When the Views OptionsView.EmptyRows option is disabled, the View automatically displays all fields when an end-user enters edit mode. Customizable Card Spacing. Use the Views OptionsView.CardIndent property to create space between cards based upon your requirements. Selection Frame Around a Selected Card. To enable this feature, activate the View's OptionsSelection.CardBorderSelection option.

Table View and Banded Table View Featuresl

Easy Column and Band Reordering. The Quick Column Customization dropdown now allows you to reorder columns. Simply drag the desired entry to a new position. The same is true for the Quick Band Customization dropdown. Use the Views OptionsCustomize.ColumnsQuickCustomizationReordering and OptionsCustomize.BandsQuickCustomizationReordering options to enable this feature. Customizable Group Summary Layout. With v6, you can display group row summaries under corresponding columns (via the Views OptionsView.GroupSummaryLayout option) and also control their horizontal alignment (via the desired columns GroupSummaryAlignment option). Group Footer Availability at the Column Level. Use a grouping column's Options.GroupFooters property to display footers for the corresponding groups. Sorting Data Groups by Group Summary Values. Refer to the Sorting Data by Group Summaries topic, for more information on this feature. Multiple Summaries per Column in the View's Footer and Group Footers. To enable this feature, use the Views OptionsView.FooterMultiSummaries and OptionsView.GroupFooterMultiSummaries options.

Common Features This section lists features which are common to all or some Views. These features are shown in no particular order.Page 5 of 3406

The ExpressQuantumGrid now uses the ExpressPageControl to display detail tabs. This means, that detail tabs now offer you the same appearance and end-user features as our advanced page control. Use the grids LevelTabs property to access appearance settings of detail tabs. Images in Detail Level Tabs. Use the grids LevelTabs.Images and LevelTabs.CaptionAlignment properties to specify the source image list and the position of tab captions. To assign images to individual tabs, use the appropriate levels ImageIndex property. To hide detail tabs whose corresponding details are empty, set a master level's Options.TabsForEmptyDetails property to False. To change the "No data to display" text, which is displayed by default in an empty View, assign the desired Views OptionsView.NoDataToDisplayInfoText property. You can handle a column or card row's OnGetCellHint event to manually provide hint text, size and position for each cell of this column or row. Alternate Captions for Columns and Card Rows. With v6, you have two options to distinguish columns and card rows that have the same caption, if they were moved to the Customization Form, Group By box or used to customize a filter condition in a filter builder dialog. You can choose from the automatic caption update dependent on the column header position (via the Views OptionsView.BandCaptionsInColumnAlternateCaption or OptionsView.CategoryRowCaptionInRowAlternateCaption property) or manually specify their captions via the corresponding column or rows AlternateCaption property. New Filter Button Behavior. By default, filter buttons are now displayed only when the mouse pointer hovers over a column header. Use the Views OptionsView.ShowColumnFilterButtons option to enable the old-style filter button behavior. Optional Column Caption Display. You can hide a column's caption within a View by setting this column's Options.ShowCaption property to False. Use the Views OptionsCustomize.ColumnFiltering option to disable filter dropdowns independently of other interface elements.

Design-Time Experiencel

Easier Access to Objects Each View now displays a triangular selector in the top-left corner. So, you can access a View directly by clicking it, instead of locating the appropriate label within the Structure Navigator. The Structure Navigator now highlights the selected View. If you select a Level by clicking the appropriate level tab, or if you select the entire grid control, the corresponding label within the Structure Navigator will be highlighted as well. Of course, highlighting also takes place when you use the Object Inspector or the Component Editor to select an object. In addition, the Structure Navigator now allows you to select multiple objects by clicking View or Level labels while holding the SHIFT key. If you select a Level or View using the Object Inspector or the grid's Structure Navigator, the corresponding View will automatically become visible within the grid control. With v6, you can access summary item properties by clicking the corresponding footer cells and summary values in group rows.

l

l

Improved Context Menus. For your convenience, grid control, View and level context menus are extended with the most frequently used actions. Column and Band Quick Customization. Column and Band Quick Customization dropdowns are now available not only to your end-users, but to you as well. These simple and effective column and band arrangement mechanisms help you get your job done quickly, without aggravation.

Known Issues and Important Changes ListWhat's New in v6

All entries in the following list are grouped by Builds, in reverse order. Build 48 Breaking Change A typo has been fixed in the TcxCustomGridOperationHelper.PerformStarndardOperation method. Now its called TcxCustomGridOperationHelper.PerformStandardOperation. Build 39 Now, if the VisibleForCustomization property of a grid item (column or card row), band, or chart item is set to False, this item or band cannot be removed by end-users from a View via the drag and drop, Quick Columns/Bands Customization dropdown, or context menu. Build 38 The parameter list has been changed in the TcxCustomGridTableController.FindNextItem, TcxCustomGridTableController.FocusNextItem and TcxCustomGridTableController.FocusNextCell methods and in the corresponding overrides of the TcxCustomGridTableControllers descendants. Build 36 Previously, the Views built-in data navigator only posted records being inserted or appended when these records were modified. This limitation has now been removed.

Grid3 and Grid4 Equivalents (alphabetically)See Also

This topic provides a conversion guide between ExpressQuantumGrid3 and ExpressQuantumGrid4 members. All members are grouped into four categories: Options, Properties, Methods and Events. Use the links under each category to access the equivalents to ExpressQuantumGrid3 members (provided in alphabetical order). Options All option names have the edgo prefix so the alphabetical order refers to option names excluding this prefix. A B CDE F HIK LM NP RS TUV Properties A B CDE F GHIK LM NOP RS TUV W Methods ABCDEFGHILMPRS Events All event names have the On prefix so the alphabetical order refers to event names excluding this prefix. ABCDEFGHIRSV Grid control The main difference between versions 3 and 4 of the ExpressQuantumGrid is that the latter is capable of displaying data within multiple Views. ExpressQuantumGrid4 provides different Views (Table, Banded Table and Card Views) for displaying data while ExpressQuantumGrid3 provides just one basic Table View (which can be displayed with or without bands). Most of the TdxDBGrid functionality is now implemented by View objects. Views present data from data fields by means of "items". An Item represents a column in Table Views and a row in Card Views. Refer to the Views and Items sections for more details. A data controller represented by the Views DataController property implements data-aware operations such as loading data, filtering, grouping and calculating summaries. Customizing colors and fonts has been delegated to Style objects and so is implemented now by assigning styles to grid elements. These changes mean that the multitude of top level properties in the grid have been replaced by a small collection of objects. While these changes provide for a more efficient and extensible product, we recognize that users of ExpressQuantumGrid3 will have initial difficulty in finding the properties required while converting event handlers for ExpressQuantumGrid4 and hence the reason for this topic. Note: the two technologies are very different so there isnt always a simple replacement available. While we have tried to cover as many options as possible, the following lists can never be totally complete (you may be using our product in ways we havent considered!). If you still have difficulty in replacing your ExpressQuantumGrid3 code because your needs are not covered here, please write to [email protected] and we will help you. Bands Unlike the previous version of the grid control, ExpressQuantumGrid4 does not contain bands by default. Instead, it provides Banded Table Views (TcxGridBandedTableView and TcxGridDBBandedTableView). A Banded Table View contains the Bands property providing a collection of TcxGridBand objects. Columns Every View provided by ExpressQuantumGrid4 contains a collection of View-specific items (columns in a (Banded) Table View and rows in a Card View) displaying data from particular fields. Unlike the previous version of the grid control, ExpressQuantumGrid4 does not provide different column types. Instead, you should use the items properties (RepositoryItem or PropertiesClass) to specify the editor type used to edit the items data. You can refer to the Data Editing Using Inplace Editors section for more information. ExpressQuamtumGrid4 provides different repository items corresponding to the ExpressQuantumGrid3 columns. These repository items can be used to specify the in-place editor type: ExpressQuantumGrid3 members ExpressQuantumGrid3 columns TdxDBGridColumn TdxDBGridBlobColumn TdxDBGridButtonColumn TdxDBGridCalcColumn TdxDBGridCheckColumn TdxDBGridCurrencyColumn TdxDBGridDateColumn TdxDBGridDropDownColumn TdxDBGridExtLookupColumn TdxDBGridGraphicColumn TdxDBGridHyperLinkColumn TdxDBGridImageColumn TdxDBGridLookupColumn TdxDBGridMaskColumn ExpressQuantumGrid4 equivalent Repository items TcxEditRepositoryTextItem TcxEditRepositoryBlobItem TcxEditRepositoryButtonItem TcxEditRepositoryCalcItem TcxEditRepositoryCheckBoxItem TcxEditRepositoryCurrencyItem TcxEditRepositoryDateItem TcxEditRepositoryExtLookupComboBoxItem TcxEditRepositoryImageItem TcxEditRepositoryHyperLinkItem TcxEditRepositoryImageComboBoxItem TcxEditRepositoryLookupComboBoxItem TcxEditRepositoryMaskItem

Nodes/records Records provided by an ExpressQuantumGrid4 View can be accessed via the ViewData property (e.g. TcxGridTableView.ViewData). TcxCustomGridRecord is the base class for items available via the ViewData object and these items consist of group rows, master and data rows, the new item row and cards. ViewData contains only those records which are currently visible or potentially visible by scrolling. It does not contain records hidden under collapsed group rows. Summary items ExpressQuantumGrid provides summary groups (as in the previous version), thus enabling you to calculate summaries when grouping by particular columns. Default summary groups are now available via the Views DataController.Summary.DefaultGroupSummaryItems property. Filter Filtering data in ExpressQuantumGrid4 is implemented by the TcxDataFilterCriteria class. It allows you to create complex filter conditions, enable/disable filter criteria and customize the filter drop-down list.

An example of registering a default editor follows: GetDefaultEditDataRepositoryItems.RegisterItem(TcxBooleanValueType, cxEditRegisteredItemsStandardVersion, GetDefaultEditRepository.CreateItem(TcxEditRepositoryCheckBoxItem)); Here, a check box is registered as the editor for items with the value type of TcxBooleanValueType. To redefine the default editor for this value type, call the RegisterItem procedure passing it the required repository item instead of TcxEditRepositoryCheckBoxItem. The second parameter of the procedure specifies the priority of the registered editor. To redefine the existing editor, you must set the parameter to a value greater than the cxEditRegisteredItemsStandardVersion. If an item is assigned to a value type not registered by RegisterItem, its editor is determined by the RegisterDefaultItem method: GetDefaultEditDataRepositoryItems.RegisterDefaultItem( cxEditRegisteredItemsStandardVersion, GetDefaultEditRepository.CreateItem(TcxEditRepositoryTextItem)); If you need to use a different editor, call RegisterDefaultItem passing it a another repository item instead of TcxEditRepositoryTextItem.

GetDefaultFieldColumnClass TCustomdxDBTreeListControl In data-aware Views, items (columns in a Table View and cards in a Card View) are assigned default editors based on the field type. An example of registering a default editor follows: GetDefaultEditDBRepositoryItems.RegisterItem(ftCurrency, cxEditRegisteredItemsStandardVersion, GetDefaultEditRepository.CreateItem(TcxEditRepositoryCurrencyItem)); Here, a currency editor represented by the TcxEditRepositoryCurrencyItem class is registered as an editor for currency fields. The first parameter specifies a value of the TFieldType enumerator. The second parameter specifies the priority of the registered editor. To redefine the existing editor, you must set the parameter to a value greater than the cxEditRegisteredItemsStandardVersion. If an item is assigned to a field not registered by the RegisterItem method, its editor is determined by the RegisterDefaultItem method: GetDefaultEditDBRepositoryItems.RegisterDefaultItem( cxEditRegisteredItemsStandardVersion,

Use the ViewInfo.GetHitTest method. This returns an object with information on the grid element containing the specified coordinates. The following code determines the record at the (X,Y) point if it falls within the content area: var

AHitTest: TcxCustomGridHitTest; ARecord: TcxCustomGridRecord;//... AHitTest := cxGrid1.ViewInfo.GetHitTest(X, Y); if AHitTest is TcxGridRecordHitTest then

ARecord := TcxGridRecordHitTest(AHitTest).GridRecord; GetNodeFooterColumnAt TCustomdxDBGrid Use the ViewInfo.GetHitTest method. This returns an object with information on the grid element containing the specified coordinates. The following code determines the column referenced within the group footer. var

See the TcxDataSummaryItem.SummaryItems property. The VisibleIndex property of the desired item. To access an individual item by its absolute index, see the Views Items property (Columns in a (Banded) Table View or Rows in a Card View). The Views Controller.GoToFirst method. The Views Controller.GoToLast method. The Views Controller.GoToNext method. The Views Controller.GoToPrev method. The Views OptionsSelection.HideFocusRect property. Call the Views Controller.EditingController.HideEdit method passing True as the Accept parameter. Use the Index property of a TcxCustomGridRecord object to get the position of the record. In unbound mode, use the Views DataController.InsertRecord method to insert a new record above the record specified as the methods parameter. In bound mode, you should use the methods of the dataset object to which the View is connected by means of a TDataSource object (for instance, the Insert method of a TDataSet descendant). Set the columns GroupIndex property to a value between 0 and GroupedColumnCount 1.

Grid control The main difference between versions 3 and 4 of the ExpressQuantumGrid is that the latter is capable of displaying data within multiple Views. ExpressQuantumGrid4 provides different Views (Table, Banded Table and Card Views) for displaying data while ExpressQuantumGrid3 provides just one basic Table View (which can be displayed with or without bands). Most of the TdxDBGrid functionality is now implemented by View objects. Views present data from data fields by means of "items". An Item represents a column in Table Views and a row in Card Views. Refer to the Views and Items sections for more details. A data controller represented by the Views DataController property implements data-aware operations such as loading data, filtering, grouping and calculating summaries. Customizing colors and fonts has been delegated to Style objects and so is implemented now by assigning styles to grid elements. These changes mean that the multitude of top level properties in the grid have been replaced by a small collection of objects. While these changes provide for a more efficient and extensible product, we recognize that users of ExpressQuantumGrid3 will have initial difficulty in finding the properties required while converting event handlers for ExpressQuantumGrid4 and hence the reason for this topic. Note: the two technologies are very different so there isnt always a simple replacement available. While we have tried to cover as many options as possible, the following lists can never be totally complete (you may be using our product in ways we havent considered!). If you still have difficulty in replacing your ExpressQuantumGrid3 code because your needs are not covered here, please write to [email protected] and we will help you. E
