Vista - WPF user controls without XAML

Does anybody know of any samples of creating and then using a WPF based user
control that does not required the use of the XAML files. The control I am
attempting to write, is too use DrawingVisuals as its for drawing some
mapping data which will contain a large number of shape objects. I have
attempted to create a control but cannot find a way of refering to it in a
WPF application, if i create an programatic instace is never displayed. All
the publications I have fond to date alays seem to use the XAML way of
programming, and donot seem to cater for large dynamic graphic controls which
wouled be butter severed with c# code.

Thansk in advance.

Why not just use dynamic XAML?

You have a couple of options for custom drawing, but neither of them involves
user controls.

You can can derive from FrameworkElement, override OnRender(), and do your
drawing there. Or, you can derive from a class like Panel and add your
visuals using AddVisualChild() and AddLogicalChild(). Just remember to
override VisualChildrenCount and GetVisual().
