Question

I have a winforms app and the main (and only) form has several buttons. When the user clicks a button, I want all other buttons to be disabled.

I know I could do this the long way by setting “Enabled” to false on all buttons but the one which has been clicked in the clicked event handler of that button, but this is a long and tedious approach.

I got the collection of controls on the form, but this does not include the several buttons I have:

        System.Windows.Forms.Control.ControlCollection ctrls = this.Controls;

How can I go about implementing this functionality in a mantainable fashion?

Thanks

Answer 1

DisableControls(Control c)
{
    c.Enable  = false;
    foreach(Control child in c.Controls)
       DisableControls(child)
}
