Occurs when a button is clicked in the Repeater control.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public event RepeaterCommandEventHandler ItemCommand
<asp:Repeater OnItemCommand="RepeaterCommandEventHandler" />

This event is raised when a button in the Repeater control is clicked.

This event causes a round-trip from the client to occur.

For more information about handling events, see Consuming Events.

The following example demonstrates how to specify and code a handler for the ItemCommand event of the Repeater control. Information about the button is displayed when a Button control within the Repeater control is clicked.
