To use a StrataFrame business object with any sort of grid (or any object that needs an IBindingList object), you need to use the BusinessBindingSource. Drop a BusinessBindingSource on the form, set the BusinessObject property on the BBS, and then set the BBS as the data soruce for the grid.As for using a mask on the grid, there is not a way to do it by default, so you'll have to create your own custom column type. MSDN has a sample on how to do this here:
