Part Manager. Web Parts Disconnected Event
Occurs after a connection between two WebPart or server controls has been terminated.
public: event System::Web::UI::WebControls::WebParts::WebPartConnectionsEventHandler ^ WebPartsDisconnected;
public event System.Web.UI.WebControls.WebParts.WebPartConnectionsEventHandler WebPartsDisconnected;
member this.WebPartsDisconnected : System.Web.UI.WebControls.WebParts.WebPartConnectionsEventHandler
Public Custom Event WebPartsDisconnected As 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.
