DataList::OnItemCommand Method (DataListCommandEventArgs^)

 

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.
