[shoaib hussain]

I am using the following code to set the datasource for combobox Column

((GridViewComboBoxColumn)radGridView1.Columns["Name"]).DataSource = from medicine in db.Medicines
                                                                                                                         select medicine;
 ((GridViewComboBoxColumn)radGridView1.Columns["Name"]).DisplayMember = "Name";
((GridViewComboBoxColumn)radGridView1.Columns["Name"]).ValueMember = "ID";

during adding new row in grid, when i click on combo column, following exception throws

but getting the following Exception

"The list must be an IBindingList to AddNew."

a quick response would be highly appreciated

thanks

Hi Shoaib Hussain,

The winforms RadGridView support adding/removing operations for objects which is implement IList/IBindingList interfaces and work like standard DataGridView. In your scenario you are using LinqToObject and it produces an IEnumerable object that does not support this functionality.
