The effect of the display is to show and hide different parts of a hierarchy - a tree with rows attached, for lack of a better way of saying it.
Let's say the display is something like this:
Category 1 Item 1 Item 2 ------ Item n Category 2 Subcategory 1 Item 1 Item 2 ...... Item n Subcategory 2 Item 1 Item 2 ...... Item n Category 3 Item 1 Item 2 ...... Item n ...... Category n
What's the best way to approach showing and hiding the category and subcategory names and the items within them? Should I tie a datagrid to a tree - or can all this be accomplished within a datagrid? Or is there another approach?
