i have a gridview which has 2 combobox columns the first one is Product group(cmbGridProGrp) which is populated from the database and i want the second combobox(cmbGridProduct) which contains products to be populated from the database based on the first combobox(cmbGridProGrp) selected value.

problem: it seems that in a combobox column inside a grid there is no selectedvalue property!!
i mean there is no "cmbGridProGrp.selectedValue"

void initProGrp()
        {
            var result = (from item in dx.tbl_ProGroups
                          orderby item.Name
                          select item);
            cmbGridProGrp.DataSource = result;
            foreach (var item in result)
            {
                cmbGridProGrp.DisplayMember = "Name";
                cmbGridProGrp.ValueMember = "ID";
            }
        }
 
        void initProduct()
        {
            try
            {
                var Products = (from item in dx.tbl_Products
                                where item.GroupID.Equals(selectedValue from cmbGridProGrp)
                                orderby item.Name
                                select item);
                foreach (var item in Products)
                {
                    cmbGridProduct.DataSource = Products;
                    cmbGridProduct.DisplayMember = "Name";
                    cmbGridProduct.ValueMember = "ID";
                }
            }
            catch
            {
                return;
            }
        }

True but you could use
DataGridViewComboBoxCell cell = row.Cells[0] as DataGridViewComboBoxCell;
if(cell != null && cell.Value != null)
// what ever you want to do with the selection
