Hi,Ken is right. You can't change the control styles that are enabled within a particular control class.
The way I have got around this in the past is to derive a control from the particular control class whose style I want to change. I then set the control style in the constructor for the subclass of the control.
I've used this to change the focus control style for labels in the past, and it seemed to work in this situation. I haven't tried this technique for other control styles or other control classes but I assume it should have the same results.

I am not sure you can change the style in c# or vb but what I have done in the past is used the mouse down event and in that event is passed a clicks value so you can test for example if the left button has been pressed how many times. with the following code in the mouse down event private void button1_MouseDown(object sender, MouseEventArgs e) { if ((e.Button==MouseButtons.Left) && (e.Clicks==2)) { } } I know that is not the DoubleClick event but I think the problem is when .net inherits the cbase control into the button it does not inherit the double click for buttons I don't know why that is but that means its not available for you. I might be wrong but the previous code in a mouse down event works fine. The previous code also will allow you to catch both single and double click and do what ever you like.

(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 buttonwas pressed, and not after the mouse button was released for finishing theclick. 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, butthe 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); } } Octavian ----- Original Message ----- From: "Jamal Mazrui" <empower@xxxxxxxxx> To: <programmingblind@xxxxxxxxxxxxx> Sent: Sunday, December 23, 2007 9:07 PM Subject: Re: click event in .netMaybe 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.

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 thinkingthat a list box should accept the click event and also accept the doubleclick event...
