Error when setting DataTable.DefaultView as ItemsSource
posted

I have a DataSet with 3 DataTables and two relations.

Like this:

Parent

Child

ChildValues

 

There is no problem, when i adding Parent.DefaultView as ItemsSource if all Tables are empty.

As soon i have one or more row in the DataSet and the grid property AddNewRowSettings.AllowAddNewRow is set to: Bottom, i getting this error:

Inner Exception Message:

When the DataSet is empty or the grid does not allow AddNewRow there is no excpetion thrown.

Whats wrong here?
