Repeater.OnItemCreated Method

Raises the ItemCreated event.

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

protected virtual void OnItemCreated(
	RepeaterItemEventArgs e
)

Parameters

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

The RepeaterItemEventArgs 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 OnItemCreated in a derived class, be sure to call the base class's OnItemCreated method.

The following example illustrates a way to handle the ItemCreated event of the Repeater control. A new line of text indicating the item type is displayed whenever a Repeater item is created.
