It might be that the border style is being overriden by something else. Are you loading a Style Library into your application? Look for "StyleManager.Load" in your code. Are you loading a layout into your grid that might be blowing away this setting? Look for LoadFromXml or LoadFromBinary or maybe just the Load method on the grid.DisplayLayout or e.Layout.
[EventSubscription(EventTopicNames.StyleChanged, ThreadOption.Publisher)] public void OnStyleChanged(object sender, ChangeStyleArgs eventArgs) { Infragistics.Win.AppStyling.StyleManager.Load(new MemoryStream(ShellApplication.ResourceManager.GetStyleFile(eventArgs.StyleLibrary))); }
