WebPartManager.Focus Method

Note: This method is new in the .NET Framework version 2.0.

Overridden to prevent focus from ever being set on the WebPartManager control, because it has no user interface (UI).

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

public:
virtual void Focus () override
public void Focus ()
public override function Focus ()

Exception typeCondition

NotSupportedException

A caller tries to call the Focus method, which is not supported in a control that has no UI.

The Focus method overrides the base Control.Focus method, and throws an exception if a caller calls the method. Because the WebPartManager control has no UI and is never visible to users, it can never allow focus to be set on itself.
