Examples

The following code example uses the Move event to display the location of the form in screen coordinates on the caption bar of the form.

   // The following example displays the location of the form in screen coordinates
   // on the caption bar of the form.
private:
   void Form1_Move( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      this->Text = String::Format( "Form screen position = {0}", this->Location );
   }

// The following example displays the location of the form in screen coordinates
// on the caption bar of the form.
private void Form1_Move(object sender, System.EventArgs e)
{
    this.Text = "Form screen position = " + this.Location.ToString();
}

' The following example displays the location of the form in screen coordinates
' on the caption bar of the form.
Private Sub Form1_Move(sender As Object, e As System.EventArgs) Handles MyBase.Move
    Me.Text = "Form screen position = " + Me.Location.ToString()
End Sub

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnMove method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnMove(EventArgs) in a derived class, be sure to call the base class's OnMove(EventArgs) method so that registered delegates receive the event.
