WPF datagrid中回车切换ComboBox焦点的问题。

datagrid中模板列用的是combobox 希望在第一行的combobox中按回车能跳到第二行的combobox

不在datagrid中的话 cbx0 跳到cbx1 就写个 cbx1.Focus 就可以了。

在datagrid中咋就不行。



 <hc:ComboBox    FocusVisualStyle="{x:Null}" IsEditable="True"  KeyDown="UIElement_OnKeyDown"   Tag="car7"   TextBox.SelectionChanged="Txtms_OnSelectionChanged1" GotFocus="Txtms_OnGotFocus" LostFocus="Txtms_OnLostFocus"  Name="cbx0"   VerticalContentAlignment="Center"  tools:BorderElement.CornerRadius="0" BorderBrush="#999999" Width="293"  tools:InfoElement.ContentHeight="50" FontSize="16px" Foreground="#1a1a1a" HorizontalAlignment="Left"  Height="50" BorderThickness="1" DockPanel.Dock="Left" />



  private void UIElement_OnKeyDown(object sender, KeyEventArgs e)

        {

            if (e.Key == Key.Enter)

            {

                ComboBox cbx = sender as ComboBox;

                Grid gr = cbx.Parent as Grid;

              

                DataGridTemplateColumn templeColumn = dg.Columns[0] as DataGridTemplateColumn;

                FrameworkElement s = dg.Columns[0].GetCellContent(dg.Items[int.Parse(gr.Tag.ToString()) + 1]);

                var tbOper = templeColumn.CellTemplate.FindName("cbx0", s) as HandyControl.Controls.ComboBox;

                //DataGridCell cell = GetCell(dg, int.Parse(gr.Tag.ToString()) + 1, 0);

                //cell.IsSelected = true;

                tbOper.Background = Brushes.Yellow;

                tbOper.Text = "123";

                tbOper.RaiseEvent(new RoutedEventArgs(ComboBox.GotFocusEvent));

            }



        }
