TreeView Rendering example Help Needed

Dear All, I am basically a Java Programmer .In Java for rendering Jcomponents like JTree,JTable getRenderedComponent method is provided.This means that whenever the component is created or updated this method is called.So this is quite useful to customizing the component. For eaxmple I could set the image icons for the JTree inside the getRenderedComponent method.I would like customize the TreeView and other C#.Net Controls with the way Java does.Can any one please help me to further with some example code. Thanks and Regards Balan.P
