Unwire event handlers on the fly

[venerable bede]

I have a checkbox on a form.
When the user checks this I want to run a routing which loops through checkboxes on a panel control and sets their checked status to the opposite so if the initial box is checked I need to uncheck all the others.
The problem is that when I check or uncheck a box its Checked event handler is fired so I end up with a stack overflow problem.
Dont ask me why I can't use a group control. I just cant in this case

This means that I have to unwire the event handler and then rewire it when I am finished.

This is what I have :

private void ChechUncheckBoxes(CheckBox cbx)
        {
           bool ticked = cbx.Checked;
            foreach (Control c in pnlSingle.Controls)
            {
                if (c is CheckBox && c.Name != cbx.Name)
                {
                    //Need to unwire here
                    ((CheckBox)c).Checked = !ticked; //this causes a stack overflow
                    //Need to rewire here
                }
            }
        }

How do I get a handle on the delegate ?



Thanks In Advance
