Control.Focus Control.Focus Control.Focus Control.Focus Method

Definition

Sets input focus to the control.

public:
 bool Focus();
public bool Focus ();
member this.Focus : unit -> bool
Public Function Focus () As Boolean

Returns

true if the input focus request was successful; otherwise, false.

Examples

The following code example sets focus to the specified Control, if it can receive focus.

public:
   void ControlSetFocus( Control^ control )
   {
      
      // Set focus to the control, if it can receive focus.
      if ( control->CanFocus )
      {
         control->Focus();
      }
   }
public void ControlSetFocus(Control control)
{
   // Set focus to the control, if it can receive focus.
   if(control.CanFocus)
   {
      control.Focus();
   }
}
Public Sub ControlSetFocus(control As Control)
   ' Set focus to the control, if it can receive focus.
   If control.CanFocus Then
      control.Focus()
   End If
End Sub

Remarks

The Focus method returns true if the control successfully received input focus. The control can have the input focus while not displaying any visual cues of having the focus. This behavior is primarily observed by the nonselectable controls listed below, or any controls derived from them.

A control can be selected and receive input focus if all the following are true: the Selectable value of ControlStyles is set to true, it is contained in another control, and all its parent controls are both visible and enabled.

The Windows Forms controls in the following list are not selectable. Controls derived from these controls are also not selectable.

Note

Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms.
