Assembly: System.Web (in system.web.dll)
The OnWebPartAdded method is called during the process of adding a WebPart control (or other server control that is added to a WebPartZoneBase zone) to a page.
Page developers can create a custom handler for the WebPartAdded event by adding the OnWebPartAdded attribute to the <asp:webpartmanager> element, and assigning a custom method name to the attribute.
