In case, someone tried to resolve my previous question, I did it like the following:

DataTemplate mycolumnDataTemplate = null;
var dataTemplateStream = new SomeClass().GetType().Assembly.GetManifestResourceStream("Some.Namespace.SomeReosurceName.xaml");
string dataTemplateString = new System.IO.StreamReader(dataTemplateStream).ReadToEnd();
dataTemplateString = dataTemplateString.Replace("[0]", browserColumn.ColumnName);
mycolumnDataTemplate = XamlReader.Load(dataTemplateString) as DataTemplate;

What are you trying to achieve? Do you want the GroupBox Height to be changed at the runtime of your application, when some event occurred or some data has changed? If so, then what you are probably looking for is a data trigger or event trigger, which you simply need to add to your DataTemplate.
