  Hi,
  
  I tried several ways to change the border colors of both radGroupBox and ContentPanel of tabItem, but no luck.
  
  Actually I would like to put the hexadecimal color "#484042" which turns out to be light gray for the borders. The following is the code I wrote for ContentPanel's border. I dont know if that is the way to go.
  
  

  ((Telerik.WinControls.Primitives.

  BorderPrimitive)(this.tabItem2.GetChildAt(1))).ForeColor = System.Drawing.Color.FromArgb(((int)(((byte)(72)))), ((int)(((byte)(64)))), ((int)(((byte)(66))))); ---> Please guide if these colors make up "#484042" since the designer generated those ARGB values when I put in the above hex value.
  
  Also, I am having a weird problem with top border of the ContentPanel. The left, right and bottom border lines appear and are visible during run time, but for some reason I dont see the upper/top border for tabItem's ContentPanel.
  
  Kindly help
  
  Thanks,
  Jayanthi

  Hello Gary,

  Thank you for contacting us.
   
  Regarding your questions:
  
  1. Please use the following code in order to customize RadGroupBox border:

  BorderPrimitive border= (BorderPrimitive)radGroupBox1.GroupBoxElement.Content.Children[1];

  border.Width = 5;

  border.BoxStyle = BorderBoxStyle.SingleBorder;

  border.GradientStyle = GradientStyles.Solid;

  border.ForeColor = Color.Red;

  
  2. This is not easy when using RadTabStrip. That is why we replaced this control with RadPageView in our latest release. I recommend that you try our latest release. Here is how you can change the content panel background in the new  version:
  

  this.radPageViewPage1.BackColor = Color.Red;

  
  Should you have any additional questions, please write back.
  

   

  All the best,
  Jack
