  Hi,
  
  I just got the newest version and was pleased to see the addition of merged column headers. However, We currently generate our ColumnGroups after a service call and while the columns show up properly, the groupColumn always shows up blank.
  
  

  public MainPage()

   {

   InitializeComponent();

   

   service.ServiceClient sc = newService.ServiceClient();

   sc.SaveFileCompleted += new EventHandler<service.SaveFileCompletedEventArgs>(sc_SaveFileCompleted);

   sc.SaveFileAsync();

  }

   

  void sc_SaveFileCompleted(object sender, fileSaveService.SaveFileCompletedEventArgs e)

  {

   RadGridView.ColumnGroups.Add(new Telerik.Windows.Controls.GridViewColumnGroup() { Name = "Vehicle_Info", Header = "Vehicle info" });

   RadGridView.ColumnGroups.Add(new Telerik.Windows.Controls.GridViewColumnGroup() { Name = "Dimensions", Header = "Dimensions" });

   

  //Further Column Definition

   

  }

  
  This will draw the columns properly, but will fail to render the columnGroups.
  
  I have attached a screenshot of what gets rendered.
  
  Secondly, we are trying to export from the grid with merged column headers and it doesnt seem to render the merged columns, I was wondering how we can get the merged columns as part of our excel export?
  
  Thanks!
  Tony

  Hi Tony,
  
  Thank you for the feedback ! I am treating these as feature requests . Both are reasonable - adding groups runtime should result in properly rendered column groups  and column groups should be included when exporting data.
  
  We have a service pack release planned within two weeks. I will do my best to have the improvements for you included.
  
  One more time thanks for the valuable feedback. I am updating your Telerik points.
  
  All the best,

  Hello Pavel
  
  The merged column headers does not yet export. Is it possible to get an estimated time of when we can expect this feature. 
  
  I am using the newest internal build at this moment: RadControls_for_Silverlight4_2011_3_1413.
  
  Thank you

  Hello Frodi,
  
  In a few hours you should be able to download our new official release (Q1 2012) which does include the feature promised earlier.
