Xceed数据网格：用键盘导航

我有一个数据网格，其使用DataTemplateSelector无论是作为文本框，组合框或滑块以显示不同的可编辑值编辑细胞。问题是我可以选中这些单元格，但无法用键盘编辑它们。我曾想象过，一旦细胞聚焦，我就可以编辑内部的物品。Xceed数据网格：用键盘导航

举例：Tab在文本框细胞>开始键入举例：Tab键滑盖细胞>现在的工作重点>使用箭头键来编辑

像现在我必须用鼠标点击开始编辑。没有办法只用键盘开始编辑。

这里是我的代码：

<UserControl.Resources> 

    <!--#region DataTemplateSelector--> 
    <local:SettingsDataTemplateSelector x:Key="SettingsDataTemplateSelector" /> 

    <DataTemplate x:Key="TextboxDataTemplate"> 
     <xcdg:MaskedTextBox IsTabStop="True" Mask="{Binding EditMask}" Text="{Binding EditValue, IsAsync=False, Mode=TwoWay, UpdateSourceTrigger=LostFocus, ValidatesOnExceptions=True}"/> 
    </DataTemplate>

            DisplayMemberPath="ValueText"> 
     </ComboBox> 
    </DataTemplate>

我结束了使用Xceed的CellEditors。如果你想用键盘编辑，似乎没有办法绕过它们。

更改EditValueVar列如下：

    <xcdg:Column FieldName="EditValueVar" Title="Edit Value" Width="150" ReadOnly="False" 
          CellEditorSelector="{StaticResource SettingsCellEditorSelector}"/>

注：删除DisplayMemberBinding，因为它可能会导致问题与动态数据

这里是CellEditors我现在使用：

<xcdg:CellEditor x:Key="maskEditor"> 
    <xcdg:CellEditor.EditTemplate> 
     <DataTemplate> 
      <xcdg:MaskedTextBox Mask="{Binding EditMask}" 
           Text="{Binding Path=(xcdg:Cell.ParentCell).DataContext.EditValue, 
               RelativeSource={RelativeSource Self}, 
               IsAsync=False, Mode=TwoWay, UpdateSourceTrigger=LostFocus, ValidatesOnExceptions=True}" 
           Style="{StaticResource {x:Type xcdg:MaskedTextBox}}"/> 
      <!--Text="{Binding EditValueText, IsAsync=False, Mode=TwoWay, UpdateSourceTrigger=LostFocus, ValidatesOnExceptions=True}"/>--> 
     </DataTemplate> 
    </xcdg:CellEditor.EditTemplate> 
    <xcdg:CellEditor.ActivationGestures> 
     <xcdg:TextInputActivationGesture /> 
    </xcdg:CellEditor.ActivationGestures> 
</xcdg:CellEditor> 

<xcdg:CellEditor x:Key="comboEditor"> 
    <xcdg:CellEditor.EditTemplate> 
     <DataTemplate> 
      <ComboBox ItemsSource="{Binding Path=(xcdg:Cell.ParentCell).DataContext.SelectionValues, 
              RelativeSource={RelativeSource Self}, UpdateSourceTrigger=PropertyChanged}" 
         SelectedValuePath="Value" 
         SelectedValue="{Binding Path=(xcdg:Cell.ParentCell).DataContext.SelectionValue, 
               RelativeSource={RelativeSource Self}, 
               UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" 
         DisplayMemberPath="ValueText" 
         Style="{StaticResource {x:Type ComboBox}}" 
         ItemContainerStyle="{StaticResource {x:Type ComboBoxItem}}"/> 
     </DataTemplate> 
    </xcdg:CellEditor.EditTemplate> 
    <xcdg:CellEditor.ActivationGestures> 
     <xcdg:KeyActivationGesture SystemKey="Down" 
            Modifiers="Alt" /> 
     <xcdg:KeyActivationGesture Key="Up" 
            Modifiers="Alt" /> 
     <xcdg:KeyActivationGesture Key="F4" /> 
     <xcdg:KeyActivationGesture Key="Space" /> 
    </xcdg:CellEditor.ActivationGestures> 
</xcdg:CellEditor> 

<xcdg:CellEditor x:Key="sliderEditor"> 
    <xcdg:CellEditor.EditTemplate> 
     <DataTemplate> 
      <Slider Value="{Binding Path=(xcdg:Cell.ParentCell).DataContext.EditSliderValue, 
          RelativeSource={RelativeSource Self}, 
          Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 
        Minimum="{Binding Path=(xcdg:Cell.ParentCell).DataContext.MinRangeValue, RelativeSource={RelativeSource Self}}" 
        Maximum="{Binding Path=(xcdg:Cell.ParentCell).DataContext.MaxRangeValue, RelativeSource={RelativeSource Self}}" 
        Style="{StaticResource {x:Type Slider}}" 
        VerticalAlignment="Bottom" 
        IsSnapToTickEnabled="True" 
        TickFrequency="1" 
        Margin="0,0,0,0"/> 
     </DataTemplate> 
    </xcdg:CellEditor.EditTemplate> 
    <xcdg:CellEditor.ActivationGestures> 
     <xcdg:KeyActivationGesture SystemKey="Right" 
           Modifiers="Alt" /> 
     <xcdg:KeyActivationGesture Key="Left" 
           Modifiers="Alt" /> 
     <xcdg:KeyActivationGesture Key="F4" /> 
     <xcdg:KeyActivationGesture Key="Space" /> 
    </xcdg:CellEditor.ActivationGestures> 
</xcdg:CellEditor>

您可能会注意到奇怪(xcdg:Cell.ParentCell) -stuff事情，是的，这是其丑无比，但这是乐git的做法。你可能有更好的运气只是用xcdg:CellEditorBinding代替。

xcdg:CellEditorBinding是结合这样的等价物：{Binding Path=(xcdg:Cell.ParentCell).Content, Mode=TwoWays, RelativeSource={RelativeSource Self}, UpdateSourceTrigger=PropertyChanged}。

我在内容之前添加了.DataContext，这是因为我的数据的结构。

希望这可以帮助别人！
