Working on an app that must allow for editing a bill of material [BOM]. The first column would be the part number, and the remaining columns would be common to all parts in the BOM, however we'd like the first column to work like a treeview. For example, when you'd first open the BOM, you would only see a single part number with a + sign to the left, and say just one column named Description with the part's description. When you click the + sign, all the part's child parts load, with their part numbers in the part number column indented one level, and with a + sign to the left of those that are assemblies, but the Description column would not be indented. How can this be done with Rad Controls?
