In .NET Windows Forms, the top-level windows do not support transparent colors. Since our ShapedForm is a top-level window (or simply a form), it does not support transparent colors as well.
However, you can set the TransparencyKey
property to the value of the BackColor
. This will make the background of ShapedForm transparent. You may also need to set the color of the border - it can be set to Transparent:
.BorderColor = Color.Transparent;
If you have additional questions, feel free to contact me.
All the best,
