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(ControlStyles.UserPaint, true);
}
protected override void OnPaint(PaintEventArgs pevent)
{
// base.OnPaint(pevent);
ControlPaint.DrawButton(pevent.Graphics,
this.ClientRectangle, toggleState);
using (Brush b = new SolidBrush(ForeColor))
{
SizeF sz = pevent.Graphics.MeasureString(Text, Font);
float x = Math.Max(2, (ClientSize.Width - sz.Width) /
2);
float y = Math.Max(2, (ClientSize.Height -
sz.Height) / 2);
pevent.Graphics.DrawString(Text, Font, b, x, y); //
draw the text on the button
}
}
protected override void OnClick(EventArgs e)
{
base.OnClick(e);
toggleState = toggleState == ButtonState.Normal ?
ButtonState.Pushed : ButtonState.Normal;
this.Invalidate();
}
ButtonState toggleState = ButtonState.Normal;
}

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.
