Hi,
I have bound XamDataGrid to a hierarchical data source and only want one column header for the root records, all expanded child table's column header is hidden, how can I achieve this? Thanks.
Did you ever find a solution to this? We have the exact same problem.
The solution we eventually reached was instead of using the child table capability in our scenario, we manually insert/remove records in the underlying data source to mimic expand/collapse behavior.
