WebPartAddingEventHandler Delegate
Represents the method that handles the WebPartAdding event of a WebPartManager object.
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 NIB: How to: Connect Event Handler Methods to Events.
