FormView Web Server Control Events

The FormView control raises a number of events in the course of paging through and updating its bound data to which your code can respond.

For an example that uses some of the FormView control events, see Modifying Data Using a FormView Web Server Control.

FormView 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.

  • ItemCreated
    Occurs after all FormViewRow objects are created in the FormView control. This event is often handled to modify the values to be displayed in a row before the row is displayed.

  • ItemDeleting
    Occurs when a Delete button (a button with its CommandName property set to "Delete") is clicked, but before the FormView control deletes the record from the data source. This event is often used to cancel the delete operation.

  • ItemDeleted
    Occurs when a Delete button is clicked, but after the FormView control deletes the record from the data source. This event is often handled to check the results of the delete operation.

  • ItemInserting
    Occurs when an Insert button (a button with its CommandName property set to "Insert") is clicked, but before the FormView control inserts the record. This event is often handled to cancel the insert operation.

  • ItemInserted
    Occurs when an Insert button is clicked, but after the FormView control inserts the record. This event is often handled to check the results of the insert operation.

  • ItemUpdating
    Occurs when an Update button (a button with its CommandName property set to "Update") is clicked, but before the FormView control updates the record. This event is often used to cancel the update operation.

  • ItemUpdated
    Occurs when an Update button is clicked, but after the FormView control updates the row. This event is often used to check the results of the update operation.

  • ModeChanging
    Occurs before the FormView control changes modes (to edit, insert, or read-only mode). This event is often handled to cancel a mode change.

  • ModeChanged
    Occurs after the FormView control changes modes (to edit, insert, or read-only mode). This event is often handled to perform a task when the FormView control changes modes.

  • DataBound
    This event is inherited from the BaseDataBoundControl control and occurs after the FormView control has finished binding to the data source.
