Hi there,
I am having a problem applying a theme to SandDock. Whenever the following code is invoked I get a NullReferenceException (stack trace at bottom)
private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
Divelements.SandDock.Rendering.Themes.SetOffice2007Theme(Divelements.SandDock.Rendering.Office2007.Office2007ColorScheme.Blue);
}
I have my suspicions that this is failing because the UserControl on which the dock resides is being loaded dynamically via reflection. This is due to the fact that the application is being developed as a Composite Application which is part of the Smart Client Software Factory (http://msdn2.microsoft.com/en-us/library/aa480482.aspx).
From what I understand each component is loaded via reflection and the application does not hold any “hard” references to each module that can be executed. I think that there must be some differences in the object hierarchy when the UserControl is loaded dynamically (a parent, container or something similar).
Any ideas on how to fix this without having an actual reference to the UserControl library?
Thanks,
Steve
