An EventArgs that contains the event data.

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.
