OnChildGridLoaded

[Orit]

In my OnChildGridLoaded
I need to do two things
1. filter the data of the child grid
2. filter the items in the ComboBoxColumn

right now I try to do only the second thing
the following happens:
I fill the ComboBoxColumn

((GridViewComboBoxColumn)((RadGridView)sender).Columns["ActivityTypeID"]).ItemsSource = ComboBoxValues.GetComboValues(dtActivityType.Select("ID < 2000"));

the comboBox is filled with the correct values
but when I select value in the comboBox
I fly
the error is 
Unable to cast object of type 'System.Data.DataRow' to type 'System.Data.DataRowView
