FormView Web Server Control Events

The FormView control raises events that occur when the current record displayed or changed. Events are also raised when a command control such as a Button that is part of the FormView control has been clicked. The following table describes the events exposed by the FormView control.

PageIndexChanging

Occurs when one of the pager buttons is clicked, but before the FormView control performs the paging operation. This event is often handled to cancel the paging operation.

PageIndexChanged

Occurs when one of the pager buttons is clicked, but after the FormView control performs the paging operation. This event is commonly handled when you need to perform a task after the user navigates to a different record in the control.

ItemCommand

Occurs when a button within a FormView control is clicked. This event is often handled to perform a task when a button is clicked in the control.
