Hi,
What i'm trying to achieve is to have a hierarchical XamdataGrid in which i can add items with the "New" context menu command, and to these items i can add child entries with the "New Detail" context menu command. And the rows should only have expanders when they have children. So far I've run into a lot of problems, for example, if i hide the + for a row who has no children, and then add child items to it, even if i set the visibility of the + back to normal, it doesn't work anymore(doesn't expand, just changes icon). I've tryed this with both collections as ObservableCollection and BindingList also.
Can you suggest a solution?
Hello,
Rather than programmatically hiding or showing the expansion indicator in the XamDataGrid, I would recommend that you set the XamDataGrid.FieldLayoutSettings.ExpansionIndicatorDisplayMode property to "CheckOnDisplay." This property will automatically show or hide the expansion indicators of the XamDataGrid on a row-by-row basis depending on whether or not that particular row has child records or not.
I have attached a sample project that adds new rows to the XamDataGrid through usage of a context menu, and this appears to work as expected. I hope this helps you.
Please let me know if you have any other questions or concerns on this matter.
