How to disable all controls on the form except for a button?

Question

My form has hundreds of controls: menus, panels, splitters, labels, text boxes, you name it.

Is there a way to disable every control except for a single button?

Based on @pinkfloydx33's answer and the edit I made on it, I created an extension method that makes it even easier, just create a public static class like this:

public static class GuiExtensionMethods
{
        public static void Enable(this Control con, bool enable)
        {
            if (con != null)
            {
                foreach (Control c in con.Controls)
                {
                    c.Enable(enable);
                }

                try
                {
                    con.Invoke((MethodInvoker)(() => con.Enabled = enable));
                }
                catch
                {
                }
            }
        }
}

Now, to enable or disable a control, form, menus, subcontrols, etc. Just do:

this.Enable(true); //Will enable all the controls and sub controls for this form
this.Enable(false);//Will disable all the controls and sub controls for this form

Button1.Enable(true); //Will enable only the Button1

So, what I would do, similar as @pinkfloydx33's answer:

private void Form1_Load(object sender, EventArgs e) 
{
        this.Enable(false);
        Button1.Enable(true);
}

I like Extension methods because they are static and you can use it everywhere without creating instances (manually), and it's much clearer at least for me.
