I need to build a DataGrid that has header rows which span the whole grid. Basically, it's an invoice and items on the invoice are grouped by type. For each group, I want to have a row which spans across the whole grid, with text that will also span across multiple columns.
I am hoping I can do this with the AdvancedDataGrid control but I haven't had much luck with the key requirement of having header rows that can span multiple columns. I also don't want it to have a tree structure. Any suggestions? Thanks
