The ItemCommand event is raised when a button within the FormView control is clicked. This allows you to provide an event-handling method that performs a custom routine whenever this event occurs.
Buttons within a FormView control can also invoke some of the built-in functionality of the control. To perform one of these operations, set the CommandName property of a button to one of the values in the following table.
CommandName value | Description |
|---|---|
"Cancel" | Cancels an edit or insert operation and returns the FormView control to the mode specified by the DefaultMode property. Raises the ModeChanged and ModeChanging events. |
"Delete" | Deletes the current record. Raises the ItemDeleted and ItemDeleting events. |
"Edit" | Puts the FormView control in edit mode. Raises the ModeChanged and ModeChanging events. |
"Insert" | Inserts the current record in the data source. Raises the ItemInserted and ItemInserting events. |
"New" | Puts the FormView control in insert mode. Raises the ModeChanged and ModeChanging events. |
"Page" | Performs a paging operation. Set the CommandArgument property of the button to "First", "Last", "Next", "Prev", or a page number to specify the type of paging operation to perform. Raises the PageIndexChanged and PageIndexChanging events. |
"Update" | Updates the current record in the data source. Raises the ItemUpdated and ItemUpdating events. |
Although the ItemCommand event is raised when a button listed in the previous table is clicked, it is recommended that you use the events listed in the table for the operation.
A FormViewCommandEventArgs object is passed to the event-handling method, which allows you to determine the command name and command argument of the button clicked. To determine the command name and command argument, use the CommandName and CommandArgument properties, respectively. You can also access the button control that raised the event by using the CommandSource property.
For more information about handling events, see NIB: Consuming Events.
For a list of initial property values for an instance of the FormViewCommandEventArgs class, see the FormViewCommandEventArgs constructor.
The following example demonstrates how to use the FormViewCommandEventArgs object passed to the event-handling method for the ItemCommand event to determine which button within a FormView control was clicked by the user.
