To do what? Is this really a grid or a container? Have you dropped this custom class on the form? I am guessing that since this is a listbox, it is really a container, and assuming the custom class has been dropped on the form. A little more info could get you a better answer.

THISFORM.grid_mun1.listboxname.MethodName()
