If you really want to disable all controls on a page, then the easiest way to do this is to set the form's Disabled property to true.

ASPX:

    

      ...
    

Code-behind:

protected void Page_Load(object sender, EventArgs e)
{
    form1.Disabled = true;
}

But of course, this will also disable your checkbox, so you won't be able to click the checkbox to re-enable the controls.
