WebPartAddingEventHandler Delegate

Represents the method that handles the WebPartAdding event of a WebPartManager object.

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

'Declaration
Public Delegate Sub WebPartAddingEventHandler ( _
	sender As Object, _
	e As WebPartAddingEventArgs _
)
'Usage
Dim instance As New WebPartAddingEventHandler(AddressOf HandlerMethod)
/** @delegate */
public delegate void WebPartAddingEventHandler (
	Object sender, 
	WebPartAddingEventArgs e
)
Not applicable.

Parameters

sender

The source of the event.

e

A WebPartAddingEventArgs that contains the event data.

The WebPartAdding event is raised by the OnWebPartAdding method just before adding a control to a Web Parts zone. This event provides an opportunity to cancel the process before it is complete. The WebPartAdded event is called after a control has been added to a Web Parts zone.

The method specified in the WebPartAddingEventHandler delegate is called when a WebPartAdding event is raised.

Page developers can provide custom handlers for the event by adding the OnWebPartAdding attribute to the <asp:webpartmanager> element in a page, and assigning a custom method name to the attribute. A custom handler can also be assigned programmatically. For more information on programmatically assigning an event handler, see How to: Connect Event Handler Methods to Events.
