Attached please find the sample "XamDataGrid_hierLayout.rar". I took the example from this thread Flat Datasource, but nested ... and tried some possible solutions for my problem.
I have a list of <product> Items bound to the XamDatagrid. Inside the class <product> is the property NestedProperty of type <NestedData>. <NestedData> contains the observable collection "WatchList". I want to display the WatchListData Elements of my NestedProperty in the DataGrid.
In the output I see no binding errors nor do i get any exceptions. The bound WatchList is shown as "(collection)" only in the grid.
Have I missed something in my xaml?
Thank you for posting on our forums.
In order to do hierarchy with alternate binding, you need to specify the dataType of the collection - IEnumerable.
I have modified the sample you attached, please have a look.
