I think the problem your running into is explained in these two lines of
the
msdn documents on DoubleClick:
By default, the ControlStyles..::.StandardClick and
ControlStyles..::.StandardDoubleClick style bits are set to false for the
Button control, and the DoubleClick event is not raised.

Subject: Re: click event in .net
Well, it doesn't happend that way. (That's why I was asking on the list
about this issue).
I have set the Click and DoubleClick events and 2 handlers for them, but
only the Click event is fired right after I pressed the mouse button.
I have tried with the num pad slash and with the real mouse button, but
only
the click event is fired.
And it is strange, because the Click event in fact is not a OnClick event,
but rather an OnMouseDown event. It is fired right after the mouse button
was pressed, and not after the mouse button was released for finishing the
click.
In this situation, of course the program doesn't know that it won't be a
click event but a double click.
Here is the test program below. If I use a button, the click is fired, but
the double click is not. But if I use a label instead, both events are
fired.
using System;
using System.Windows.Forms;
class MyForm : Form {
public MyForm() {
this.Text = "Test form";
Button button = new Button();
button.Text = "Ok";
button.Click += delegate(Object sender, EventArgs e) { this.Text = "Click
is
ok"; };
button.DoubleClick += delegate(Object sender, EventArgs e) {
MessageBox.Show("the double click is working."); };
this.Controls.Add(button);
/*
Label label = new Label();
label.Text = "The label";
label.Click += delegate(Object sender, EventArgs e) { this.Text = "The
click
is ok"; };
label.DoubleClick += delegate(Object sender, EventArgs e) {
MessageBox.Show("The double click is working."); };
this.Controls.Add(label);
*/
}
}
class Test {
static void Main() {
Form form = new MyForm();
Application.Run(form);
}
}

Maybe we are just saying it differently -- I think a .NET control can
handle both events, but the click event will fire twice, once on its own
and once when the double click event fires.

Ok, thanks. So it seems that a control in a .net application cannot
handle
both the click and the doubleClick events.
However I think that this is not true for all the controls... I am
thinking
that a list box should accept the click event and also accept the double
click event...
