hi -- I have two panels that are added to a tab control that make up the primary division of my windows form application. The right hand panel (called graph_panel) will draw appropriately when a Graphics object is created, attached to the graph_panel. However, based on a parameter passed to the method, i want to add a child panel (programmatically), create a Graphics object, and put some lines in the child panel. when going into run, the child panel flickers briefly and then whatever is drawn disappears. Does anybody know what limitations there are to creating a child panel as a graphics container?
