Assembly: System.Web (in System.Web.dll)
The method raises the WebPartsDisconnecting event, which occurs when two controls are ending a connection. The method provides the opportunity to cancel the disconnection process. If the connection is successfully removed, the WebPartsDisconnected event follows.
Page developers can provide a custom handler for the associated event by adding the OnWebPartsDisconnecting attribute to the <asp:webpartmanager> element on a Web page, and then assigning a custom method name to the attribute.Notes to Inheritors:
Developers who create derived WebPartManager classes can override the method to customize the event handling.
