Assembly: System.Web (in System.Web.dll)
The method raises its corresponding event at the very end of the DisconnectWebParts method, which carries out the process of terminating a connection between two controls.
The method provides programmatic control over the process of ending a connection, so that developers can inform the user, make changes to the user interface (UI), or make other changes to the application.
Page developers can create a custom handler for the WebPartsDisconnected event by adding the OnWebPartsDisconnected attribute to the <asp:webpartmanager> element, and assigning a custom method name to the attribute.
