Repeater.OnItemCommand Method

Raises the ItemCommand event.

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

protected virtual void OnItemCommand(
	RepeaterCommandEventArgs e
)

Parameters

e
Type: System.Web.UI.WebControls.RepeaterCommandEventArgs

The RepeaterCommandEventArgs object that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Consuming Events.

Notes to Inheritors

When overriding OnItemCommand in a derived class, be sure to call the base class's OnItemCommand method.

The following example illustrates a way to handle an ItemCommand event of the Repeater control. Information about the button is displayed whenever a Button control within the Repeater control is clicked.
