Common things should care- Arrange all controls in common manner.

- Use same font and sizes to all pages (Arial, Georgia, Time new Roman).

- Text aligning ,spelling and grammar mistakes.- Lower case and upper case strategy (Initials

should be in upper case).- All read-only fields avoided in the TAB

sequence.- Sort data in combo boxes and list boxes to

ascending order.

Common things should care…cont- All error messages should display as follows,

Text Box – Please enter value for employee Id Combo box/List box/calendar – Please select the department - Focus of error messages should set to related

field.- Define standard size for all text boxes.- Text Area control should fit to the form.

Common things should care…cont- Number of characters for text boxes should limit

according to the database column size.- Fit all controls to the form/page, because all

controls are messing up when the browser getting smaller (squeezing).

- When squeezing window use horizontal scroll bar.

- Show creation, search and list in single page then no need to add separate menu to show list.
