How do you create a multi-column datagrid?
I have a collection of data in a data master called Albums. There are two fields, Albums.Name (text field) and Albums.Art (a file). I want them displayed in a grid that is 3 columns wide x N rows, where N is "as many as needed." See the attached image for the layout I'm trying to achieve.
So far, everything I do just results in three copies of a 1xN grid, with the data repeated in each column. The web store example Clothes screen seems to do what I want, but I can't figure out how it works.
