ToolbarButton toggling

RighteousManUP · October 17th, 2003, 11:42 AM

The code will compile, but when I run it, the debugger throws an exception claiming invalid cast exception for the, "int button in," part of the foreach loop. If I do toolBar1.Buttons[1].Pushed = true; as a test, the code has no problem setting the second button to toggled on. The goal of this foreach loop is to turn all the buttons to a non-toggled state, then it will set the button that was clicked to a toggled state. I need to do this in order to keep a mutually exclusive setting for the buttons which represent draw modes. So what is going on?

            foreach (int button in toolBar1.Buttons)
            {
                toolBar1.Buttons[button].Pushed = false;
            }

            toolBar1.Buttons[ButtonClicked].Pushed = true;

Thanks,
Jon

Hi Jon,

I think this is caused by the fact that the Buttons collection does not return a collection of ints, but a collection of buttons:

Code:

foreach (Button myButton in toolBar1.Buttons)
{
  myButton.Pushed = false;
}
toolBar1.Buttons[ButtonClicked].Pushed = true;

This code will loop through the Buttons collection, and each reference to a button is assigned to MyButton. This means you can treat MyButton as a real button (which it is) and simply use its Pushed property.

HtH,

Imar
