WebPartManager.Focus Method

Definition

Namespace:

System.Web.UI.WebControls.WebParts

Assembly:

System.Web.dll

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

public:
 override void Focus();

public override void Focus ();

override this.Focus : unit -> unit

Public Overrides Sub Focus ()

Exceptions

NotSupportedException

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

Remarks

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.
