COMBOBOX单元格报错

一个COMBOBOX单元格始终显示的是ID值，不显示name值，当选择下一个单元格的时候报错
combo_Stock.ValueMember = "ID";
combo_Stock.DisplayMember = "Name";

需要设置ComboBox的DataSource属性。
DataSource中应该包含两列。一列是ID，一列是Name。

Private Sub gcMultiRow1_DataError(ByVal sender As Object, ByVal e As DataErrorEventArgs) Handles GcMultiRow1.DataError

        ' The first id cell only can input number, if user input some invalid value, DataError event will be fired.
        ' You should handle this event to handle some error cases.
        If (e.Context And DataErrorContexts.Commit) <> 0 Then
            ' When committing value occurs error, show a massage box to notify user, and roll back value.
            MessageBox.Show(e.Exception.Message)
            EditingActions.CancelEdit.Execute(Me.gcMultiRow1)
            ' Other handle.
        Else
        End If
    End Sub
