DataList::OnItemCommand Method

Raises the ItemCommand event. This allows you to provide a custom handler for the event.

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

protected:
virtual void OnItemCommand(
	DataListCommandEventArgs^ e
)

Use the OnItemCommand method to provide a custom handler for the ItemCommand event.

The ItemCommand event is raised when any button is clicked in the DataList control and is commonly used when you have a button control with a custom CommandName value, such as Add, in the DataList control.

Raising an event invokes the event handler through a delegate. For more information, see How to: Consume Events in a Web Forms Application.

The OnItemCommand method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnItemCommand in a derived class, be sure to call the base class's OnItemCommand method so that registered delegates receive the event.

The following code example demonstrates how to specify and code a handler for the ItemCommand event to select an item from the DataList control.

The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Page Code Model.
