The OnWebPartsConnected method raises its corresponding event at the very end of the ConnectWebParts method, which ensures that the steps necessary to connect two controls are completed before any code in the event handler runs.
The method provides programmatic control over the process of creating connections, and the associated event is a convenient point at which to update the user interface (UI) or notify a user that a connection has been established.
Page developers can create a custom handler for the WebPartsConnected event by adding the
OnWebPartsConnected attribute to the
<asp:webpartmanager> element, and assigning a custom method name to the attribute.
