  Hi,
  
  we’re currently implementing the C1Themes. As a basis we use the standard themes, that are provided by ComponentOne.
  
  When we select for example the VS2013Tan theme in the C1ThemeDesigner and select WinForms in the Theme tree, then we can see the sample Form with the WinForms controls. There are several standard GroupBoxes on the Form, but the border of the GroupBoxes are very hard to spot. They are visible, but in a light gray on the light tan background. Unfortunately I’ve not found the correct place in the Theme tree, where I can change this border color of the GroupBox. Could someone give me a hint?
  
  Thanks in advance and best regards,
  
  Juergen

  Hi Juergen,

  this is not possible. This question can be found on the web, and the only solution is to add custom Paint code: https://stackoverflow.com/questions/76455/how-do-you-change-the-color-of-the-border-on-a-group-box

  The only workaround would be if C1 created a custom “C1GroupBox” control (as they did for C1Label or C1TextBox).

  Best regards

  Wolfgang

  Hi Wolfgang,

  thanks a lot! I had the hope, that there might be an easier solution, that switching to Themes from the old VisualStyles wouldn’t be so painful, but ok - I’m going to create my own GroupBox, that will handle the Themes.
  
  I would, however, vote for a C1GroupBox from ComponentOne in a future release

  Best regards,
  
  Juergen
