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)

public delegate void WebPartAddingEventHandler(
	Object sender,
	WebPartAddingEventArgs e
)

Parameters

sender
Type: System.Object
The source of the event.
e
Type: System.Web.UI.WebControls.WebParts.WebPartAddingEventArgs
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.
