Control.VisibleChanged Control.VisibleChanged Control.VisibleChanged Control.VisibleChanged Event


Occurs when the Visible property value changes.

 event EventHandler ^ VisibleChanged;
public event EventHandler VisibleChanged;
member this.VisibleChanged : EventHandler 
Public Custom Event VisibleChanged As EventHandler 


The following code example raises the VisibleChanged event when the Visible property value of the Label control has changed.

   void Button_HideLabel( Object^ /*sender*/, EventArgs^ /*e*/ )
      myLabel->Visible = false;

   void AddVisibleChangedEventHandler()
      myLabel->VisibleChanged += gcnew EventHandler( this, &MyForm::Label_VisibleChanged );

   void Label_VisibleChanged( Object^ /*sender*/, EventArgs^ /*e*/ )
      MessageBox::Show( "Visible change event raised!!!" );
private void Button_HideLabel(object sender, EventArgs e)
   myLabel.Visible = false;

private void AddVisibleChangedEventHandler()
   myLabel.VisibleChanged += new EventHandler(this.Label_VisibleChanged);

private void Label_VisibleChanged(object sender, EventArgs e)
   MessageBox.Show("Visible change event raised!!!");
Private Sub Button_HideLabel(ByVal sender As Object, ByVal e As EventArgs)
   myLabel.Visible = False
End Sub 'Button_HideLabel

Private Sub AddVisibleChangedEventHandler()
   AddHandler myLabel.VisibleChanged, AddressOf Label_VisibleChanged
End Sub 'AddVisibleChangedEventHandler

Private Sub Label_VisibleChanged(ByVal sender As Object, ByVal e As EventArgs)
   MessageBox.Show("Visible change event raised!!!")
End Sub 'Label_VisibleChanged


This event is raised if the Visible property is changed by either a programmatic modification or user interaction.
