Control.Focus Method

Sets input focus to the control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

'Declaration
Public Function Focus As Boolean
'Usage
Dim instance As Control 
Dim returnValue As Boolean 

returnValue = instance.Focus()

Return Value

Type: System.Boolean
true if the input focus request was successful; otherwise, false.

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.

NoteNote:

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.

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