Hi, I just created a simple WCF application and tried to override OnRender method: protected override void OnRender(DrawingContext drawingContext) { base.OnRender(drawingContext); FormattedText ft = new FormattedText("Hello World", System.Globalization.CultureInfo.CurrentUICulture, FlowDirection.LeftToRight, new Typeface("Arial"), 10.0, Brushes.Black); drawingContext.DrawText(ft, new Point(10, 10)); } However, I don't see anything being drawn on the screen. Am I missing something? Thank you in advance for your help. Pradeep |

Hello, If you're trying to OnRender a Window, wel... this is a little different than a FrameworkElement (from wich the OnRender is inherited) and elements in WPF are more than different from the Winforms approach ( I think you are trying to make an analogy with OnPaint). This is because of WPF architecture. You should check out this MSDN article http://msdn2.microsoft.com/en-us/library/ms748373.aspx it's very detailed about the differences between immediate mode graphic systems (Win32) and retained mode graphic systems (WPF). If you're making a custom control, then I've just implemented it and it works fine.
