Radgridview issue

Hi,

I have three GridViewComboBoxColumn in RadGridView. Each Combobox column has display name and selected value code. When I assign the value, corresponding values are assigning correctly. But when when I fetch the row, Code value is coming as null and code value is displaying in name. I have attached the image.

The following code I have used to bind data to GridViewComboBoxColumn.

 ((GridViewComboBoxColumn)this.dataGrid.Columns["Company_Name"]).ItemsSource = CompanyList;
 ((GridViewComboBoxColumn)this.dataGrid.Columns["Company_Name"]).DisplayMemberPath = "Company_Name";
 ((GridViewComboBoxColumn)this.dataGrid.Columns["Company_Name"]).SelectedValueMemberPath = "Company_Code_Hdn";
