how do you make a button stay depressed

[Peted]

take away its prozac ?
no seriously
I want to drop a button onto a form, then during runtime, when user
clicks the button it stays in the "depressed" image state (with a new
color) then when it is pressed again it pops up to its normal state
and color
and of course i want to execute code on each push down and pop up

any idea how this can be done please.
Also a way to make an array of such depresseable buttons, that
function like an array of radio buttons in that only 1 on the panel is
ever selected at any one time
thanks for any advice

One way os to use the ControlPaint class and draw the button yourself.

public class ToggleButton : Button
{
public ToggleButton()
{
SetStyle(Contro lStyles.UserPai nt, true);
}
protected override void OnPaint(PaintEv entArgs pevent)
{
// base.OnPaint(pe vent);
ControlPaint.Dr awButton(pevent .Graphics,
this.ClientRect angle, toggleState);
using (Brush b = new SolidBrush(Fore Color))
{
SizeF sz = pevent.Graphics .MeasureString( Text, Font);
float x = Math.Max(2, (ClientSize.Wid th - sz.Width) /
2);
float y = Math.Max(2, (ClientSize.Hei ght -
sz.Height) / 2);
pevent.Graphics .DrawString(Tex t, Font, b, x, y); //
draw the text on the button
}
}
protected override void OnClick(EventAr gs e)
{
base.OnClick(e) ;
toggleState = toggleState == ButtonState.Nor mal ?
ButtonState.Pus hed : ButtonState.Nor mal;
this.Invalidate ();
}
ButtonState toggleState = ButtonState.Nor mal;
}

This seems like check box functionality. Why not to use checkbox
instead with its Appearance property set to Button?

Same thing: radio button has Appearance property which can be set to
Button making it look like push button.
