Suppose we open a form then the following triggers are executed:-

• PRE-LOGON
• ON-LOGON
• POST-LOGON
• PRE-FORM
• PRE-BLOCK
• WHEN-NEW-FORM-INSTANCE
• WHEN-NEW-BLOCK-INSTANCE
• WHEN-NEW-ITEM-INSTANCE
• Now the cursor is placed on the first item of the Block.
• Suppose if we type some data and press the Tab key then the following sequence of triggers fires:-
• KEY-NEXT-ITEM (This trigger is present on the item level).
• POST-CHANGE (This trigger is present on the item level).
• WHEN-VALIDATE-ITEM (This trigger is present on the item level).
• POST-TEXT-ITEM (This trigger is present on the item level).
• WHEN-NEW-ITEM-INSTANCE (Block Level Trigger).
• The cursor goes to the next item present on the screen.
• If suppose there are no further items present on the screen them if we enter data and press tab key then only KEY-NEXT-ITEM is fired. Now suppose we close the form then the item level triggers (explained above) are fired.
• POST-BLOCK
• POST-FORM
• Now the form gets closed.
