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.
