I am using WPF toolkit:Datagrid and using EDM as its itemsource.
EDM designer class is giving me an error while I change the first cell in the grid.
It's property is getting binded to the source.
It is giving me an error = "This property cannot be set to a null value."

dgFinancialYear.Columns.Add(new Microsoft.Windows.Controls.DataGridTextColumn { Header = "Financial Year", Binding = new Binding { Path = new PropertyPath("FinancialYear"),  ValidatesOnExceptions = true, ValidatesOnDataErrors = true,  UpdateSourceTrigger = System.Windows.Data.UpdateSourceTrigger.PropertyChanged, NotifyOnSourceUpdated = true, }, Width = 160 });


Above is the code for the grid column and there is no any cell change or cell edit ending event in WPF toolkit:Datagrid


Any help will be highly appreciated.
