Thank you for contacting Syncfusion support.
In GroupBar Control, the Border Color customization will be serialized once it is modified and then Visual Style customization code will be serialized.
Border Style customization
Visual Style Customization
Figure 4: Visual style to Metro.
As Serialized code snippet in Form Designer.cs, Visual Style code snippet applied after the Border Color customization, So default Border Color customization defined for chosen Visual Theme will be applied. So Border Color defined in sample designer will be overridden.
So this is not an issue and this problem can be resolved by setting the Border color through code after Visual Style customization is applied.
Please refer the following code snippet,
//set Border Color
this.groupBar1.BorderColor = Color.Red;
After running the Border color is displayed.
We have also prepared the sample for your reference. It can be downloaded from the following Link.
