RadButton's Border does not show

[Jason]

I have set the button's top border color to be red and bottom border color to be yellow by the below codes but the appearance never show the border colors when running.

            this.ButtonElement.BorderElement.BoxStyle = BorderBoxStyle.FourBorders;
            this.ButtonElement.BorderElement.TopColor = Color.Red;
            this.ButtonElement.BorderElement.TopWidth = 2;
            this.ButtonElement.BorderElement.BottomColor = Color.Yellow;
            this.ButtonElement.BorderElement.BottomWidth = 2;

Please help me to solve this problem.

Hi Jason,

Thank you for contacting us.

You need to set the PaintUsingParentShape property to false. Please refer to the example below how to achieve it: 

this.radButton1.ButtonElement.BorderElement.PaintUsingParentShape = false;
this.radButton1.ButtonElement.ShowBorder = true;
this.radButton1.ButtonElement.BorderElement.BoxStyle = BorderBoxStyle.FourBorders;
this.radButton1.ButtonElement.BorderElement.TopColor = Color.Red;
this.radButton1.ButtonElement.BorderElement.TopWidth = 2;
this.radButton1.ButtonElement.BorderElement.BottomColor = Color.Yellow;
this.radButton1.ButtonElement.BorderElement.BottomWidth = 2;
this.radButton1.ButtonElement.BorderElement.LeftColor = Color.Blue;
this.radButton1.ButtonElement.BorderElement.LeftWidth = 3;
this.radButton1.ButtonElement.BorderElement.RightColor = Color.Green;
this.radButton1.ButtonElement.BorderElement.RightWidth = 3;

In the attachments you can find an image demonstrating the result on my end.

Should you have further questions, I would be glad to help.
