Raises the ConnectionsActivating event to indicate that a page and its controls have loaded, and the process of activating connections can begin.
Assembly: System.Web (in System.Web.dll)
The method raises the ConnectionsActivating event, which provides developers with a mechanism for programmatically customizing the process of activating connections.
Page developers can add a custom handler for the event by adding an OnConnectionsActivating attribute to the <asp:webpartmanager> element in a page, and then assigning a custom method name to the attribute.Notes to Inheritors
Developers can override the method in a derived WebPartManager class.
