I'm looking at your demo for the PropertyGrid Editor Attribute. MapEditorControl.xaml is a UserControl which is set as an editor in Employee.cs using
[Telerik.Windows.Controls.Data.PropertyGrid.Editor(typeof(MapEditorControl), "Location", Telerik.Windows.Controls.Data.PropertyGrid.EditorStyle.Modal),]
public string Location
if (this.location != value)
this.location = value;
However, when you run the demo the UserControl MapEditorControl sits inside another Window (see attached image). How do I access this window to set header text, icons and themes?
Based on the demo it seems I can only access the UserControl and so any implicit themes will only work from here onward and not on it's parent window.
