Property Value

true if the control can receive focus; otherwise, false.

In order for a control to receive input focus, the control must have a handle assigned to it, and the Visible and Enabled properties must both be set to true for both the control and all its parent controls, and the control must be a form or the control's outermost parent must be a form.

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

Visual Basic
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
C#
public void ControlSetFocus(Control control)
{
   // Set focus to the control, if it can receive focus.
   if(control.CanFocus)
   {
      control.Focus();
   }
}
C++
public:
   void ControlSetFocus( Control^ control )
   {
      
      // Set focus to the control, if it can receive focus.
      if ( control->CanFocus )
      {
         control->Focus();
      }
   }
J#
public void ControlSetFocus(Control control)
{
    // Set focus to the control, if it can receive focus.
    if (control.get_CanFocus()) {
        control.Focus();
    }
} //ControlSetFocus
