It's the beauty of inheritance Smile | :)

OK. Lets see how/why I say that Smile | :)

1. What we want is a button that we can programatically fire events. It makes sense to add this functionality to the Button class. So we make one:

public class ButtonEx():System.Windows.Forms.Button
{
  public void CallButtonclick()
  {
    base.OnClick(EventArgs.Empty); // sorry mistake in first post :)
  }
}

2. We replace our existing Button in the in the form with our new ButtonEx.

private System.Windows.Forms.Button button1; //now becomes
private ButtonEx button1;

And in the windows forms designer region, change :
button1 = new System.Windows.Forms.Button(); //now changes to
button1 = new ButtonEx();

Be sure to save before viewing in the designer(in fact close it beforehand, it does more harm than good Laugh | :laugh: ).

3. Finally we just call our new ButtonEx's CallButtonClick methods as follows:

button1.CallButtonClick();


NOTE: If you'll be calling this method from thread u will need to invoke it. I'm not 100% sure, but it would look something like this:

button1.Invoke( new MethodInvoker(button1.CallButtonClick));


Hope this adds some insight Smile | :)

Give them a chance! Do it for the kittens, dear God, the kittens!
