For Hierarchical Data display is it possible to catch Row Expanded and Row Collapsed event? I want to do lazy loading for the child records. On these events I would like to fetch the data and dynamically add to the source. Please help.
I haven't tried this myself. I would use the RecordExpanding event of the XamDataGrid to load child data for that parent record into the data source. I would avoid removing it, but if I had to do so, I'd do it in the RecordCollapsed event.
