GridMultiColumnDropDownList with ItemSourceSelector throws NullException while editing

GridMultiColumnDropDownList with ItemsSourceSelector throws NullException after editing second cell.


Steps to reproduce:

Create SfDataGrid with GridMultiColumnDropDownList and specify ItemsSourceSelector.


After running application:

1. eddit first row and select value (works fine),

2. edit second row and select value(throws exception)


I have provided simple wpf application.

Just run and try editing both rows as I wrote before
