  Hello,
  I hope that someone can help me with this little issue.
  I would like to change the color of a GroupBox Header back to the applied theme's default color.
  
  I prgrammatically changed the border color with the following code to red to show an invalid user input (a kind of validation).
  

  
  DirectCast(.rgrb_CountryOfOrigin.GroupBoxElement.Children(1).Children(1), BorderPrimitive).ForeColor = Color.Red 

  
  When the input is corrected the color should change back to its default value. Actually I use the desert theme.
  Is there a possibillity to get a default color value for the assigned theme for the chosen control (eg GroupBox)?
  If not, where can I find the theme values like colors etc?
  Any help is appreciated.
  Cheers Roberto

  Hello Roberto,
  
  You can reset any values in the Telerik Presentation Framework by calling the ResetValue method and passing the property that you want to reset. In this case.
  
  

  DirectCast(Me.RadGroupBox1.GroupBoxElement.Children(1).Children(1), BorderPrimitive).ResetValue(LightVisualElement.ForeColorProperty, Telerik.WinControls.ValueResetFlags.Local)

  
  Hope you find that helpful
  Richard
