WebPartManager.WebPartsDisconnected Event

Occurs after a connection between two WebPart or server controls has been terminated.

Namespace:  System.Web.UI.WebControls.WebParts
Assembly:  System.Web (in System.Web.dll)

public event WebPartConnectionsEventHandler WebPartsDisconnected
<asp:WebPartManager OnWebPartsDisconnected="WebPartConnectionsEventHandler" />

The WebPartsDisconnected event is associated with the OnWebPartsDisconnected method. The event is useful because after you know that a connection is terminated, you might want to inform the user, perform some cleanup actions in the code, or make other changes in the user interface (UI).

Page developers can associate a custom event handler with this event by adding the OnWebPartsDisConnected attribute to the <asp:webpartmanager> element in the page, and assigning a custom method name to the attribute.
