I've written a module to export data from a WinForm RadGridView to excel. The module handles grouping as well. Now that we have ported over to WPF, that module doesn't work anymore.Below are the RadGridView Winform objects, properties or methods. What are the equivalents in WPF? GridViewChildRowCollection GridViewRowInfo row.ChildRows row.Group row.HierarchyLevel row.Group.GroupRow.HierarchyLevel DataGroupCollection DataGroupgroup.Groups.Count grid.ColumnCount
