Hi,
The simple way would be ..
class BorderlessButton:Button
{
protected override void OnPaint(PaintEventArgs pevent)
{
base.OnPaint(pevent);
pevent.Graphics.DrawRectangle(new Pen(this.BackColor,5), this.ClientRectangle);
}
}
Once you compile this class. it will be available in the tool box. Drag to form. Set flat style. Display your image.
