Hi Youki,
Thanks for contacting Syncfusion support.
You can resolve this by setting same color for the properties Style.TitleBar.BackColor and Style.TitleBar.BottomBorderColor as shown in the following code example.
Code example :
//Sets the back color and fore color of the title bar.
this.Style.TitleBar.BackColor = Color.Black;
this.Style.TitleBar.ForeColor = Color.White;
//Set bottom border color for TitleBar
this.Style.TitleBar.BottomBorderColor = Color.Black; |
Please let us know if you require any other assistance from us.
Regards,
Mohanram A.
