ProxyWebPartManager.Focus Method

Overrides the base method to prevent the method from being called.

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

public override void Focus()

ExceptionCondition
NotSupportedException

A caller tries to call this method.

The Focus method overrides the base method and throws an exception if any caller attempts to call the method. This is because the inherited Control.Focus method is designed for controls with a user interface (UI), but the ProxyWebPartManager control has no UI and therefore has no need to set the focus.
