If you using roweditending or anything related to the corresponding datagrid during reload add like this depending on your names...
System.Windows.Data.CollectionViewSource t_productViewSource = ((System.Windows.Data.CollectionViewSource)(this.FindResource("t_productViewSource")));
t_productViewSource.View.MoveCurrentToFirst();

**I seen this error in 3 cases**

**case1** : this error shown if double clicking the datagrid then(custom datagrid which contains processed data like analysis)

Simply, Set in Datagrid IsReadOnly="True"

**case2** : this error shown after editing the datagrid, must set during RowEditEnding

(sender as DataGrid).CommitEdit(DataGridEditingUnit.Row);

**case3** : this error shown after RowEditEnding event, then must see where the datagrid is reloading the data, it can happen if viewsource or datagrid is already in use and we try to override the data manually

Let me know if any new cases you seen
