                    ComboMovePlace.ValueMember = "Move_id";
                    ComboMovePlace.DisplayMember = "Move_Place";

推荐答案

试试这个

try this

int index = 0; // index of the combox box column ( zero based index )
           foreach (DataGridViewRow row in dataGridView1.Rows)
           {
               var cbxMove = row.Cells[index] as DataGridViewComboBoxCell;
               cbxMove.ValueMember = "Move_id";
               cbxMove.DisplayMember = "Move_Place";
               cbxMove.DataSource = dSet.Tables[0];
           }
