Hello,

On a form, I place a buton with an OnClick event.  No problem.

I set the visible propperty of this button to false.
And reset it so true again,  the event isn't fired ans my app same to be
crashed ...

Any idea?

Thx

Can you clarify?
Do you mean that you subscribe to the Click event?
Do you mean that subsequently clicking the Button has no effect?
In what way?

What framework version? (1.1, 2.0?)

Are you doing anything unusual? threading?

The following works fine:

    static void Main() {
        using (Form f = new Form())
        using (Button b1 = new Button())
        using (Button b2 = new Button()) {
            b1.Text = "Toggle visible";
            b2.Text = "Click me";
            b1.Click += delegate { b2.Visible = !b2.Visible; };
            b2.Click += delegate { f.Text += " [click]"; };
            b1.Dock = b2.Dock = DockStyle.Top;
            f.Controls.AddRange(new Control[] {b2, b1});
            Application.Run(f);
        }
    }
