如何禁用WPF數據網格中的文本塊邊界？

我面臨着一個問題TextBlock in DataGrid。我無法禁用邊框對於TextBlock。還有沒有物業與名稱BorderThickness對於TextBlock。
那麼我們怎樣才能禁用一個TextBlock的邊框。如何禁用WPF數據網格中的文本塊邊界？

在這裏，我將我的樣本網格單元格樣式

       <DataGrid.CellStyle> 
            <Style TargetType="DataGridCell"> 
             <Style.Triggers>            
              <Trigger Property="IsKeyboardFocusWithin" Value="True"> 
               <Setter Property="BorderBrush" Value="DarkTurquoise" /> 
               <Setter Property="IsSelected" Value="True"/> 
               <Setter Property="BorderThickness" Value="0"/> 
              </Trigger> 
             </Style.Triggers> 
            </Style> 
           </DataGrid.CellStyle>

在這裏，我將我的整個DataGrid的代碼

<DataGrid Name="gridcancelled" ItemsSource="{Binding}" HeadersVisibility="None" IsReadOnly="True" AutoGenerateColumns="False" GridLinesVisibility="Horizontal" Background="White" Cursor="Hand" MouseLeftButtonDown="gridcancelled_MouseLeftButton" Loaded="gridcancelled_Loaded" PreviewKeyDown="gridcancelled_PreviewKeyDown" RowHeight="44.9" SelectedIndex="0" HorizontalGridLinesBrush="{StaticResource BlueGridLine}" VerticalGridLinesBrush="{StaticResource BlueGridLine}" BorderThickness="1.5,1,1,1" BorderBrush="Gray"> 

           <DataGrid.CellStyle> 
            <Style TargetType="DataGridCell"> 
             <Style.Triggers>            
              <Trigger Property="IsKeyboardFocusWithin" Value="True"> 
               <Setter Property="BorderBrush" Value="DarkTurquoise" /> 
               <Setter Property="IsSelected" Value="True"/> 
               <Setter Property="BorderThickness" Value="0"/> 
              </Trigger> 
             </Style.Triggers> 
            </Style> 
           </DataGrid.CellStyle> 

           <DataGrid.Resources> 
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="DarkTurquoise"/> 
            <Style TargetType="{x:Type DataGridRow}"> 
             <Style.Triggers> 
              <Trigger Property="IsMouseOver" Value="true"> 
               <Setter Property="Foreground" Value="White" /> 
               <Setter Property="Background" Value="DarkTurquoise" /> 
               <Setter Property="FontSize" Value="14"></Setter> 
               <Setter Property="FontWeight" Value="Medium"></Setter> 
              </Trigger> 
              <Trigger Property="DataGridRow.IsSelected" Value="True"> 
               <Setter Property="Foreground" Value="White" /> 
               <Setter Property="Background" Value="DarkTurquoise" /> 
               <Setter Property="FontSize" Value="14"></Setter> 
               <Setter Property="FontWeight" Value="Medium"></Setter> 
              </Trigger> 
             </Style.Triggers> 
            </Style> 
           </DataGrid.Resources> 

           <DataGrid.Columns> 
            <DataGridTextColumn Binding="{Binding billId}" Width="220"> 
             <DataGridTextColumn.ElementStyle> 
              <Style TargetType="TextBlock"> 
               <Setter Property="VerticalAlignment" Value="Center" />           
              </Style> 
             </DataGridTextColumn.ElementStyle> 
            </DataGridTextColumn> 
             <DataGridTextColumn Binding="{Binding billDate}" Width="210" > 
              <DataGridTextColumn.ElementStyle> 
              <Style TargetType="TextBlock"> 
               <Setter Property="VerticalAlignment" Value="Center" /> 
               </Style> 
             </DataGridTextColumn.ElementStyle> 
            </DataGridTextColumn> 
            <DataGridTextColumn Binding="{Binding counterId}" Width="210"> 
             <DataGridTextColumn.ElementStyle> 
              <Style TargetType="TextBlock"> 
               <Setter Property="VerticalAlignment" Value="Center" /> 
               </Style> 
             </DataGridTextColumn.ElementStyle> 
            </DataGridTextColumn> 
             <DataGridTextColumn Binding="{Binding cashierId}" Width="190" > 
              <DataGridTextColumn.ElementStyle> 
              <Style TargetType="TextBlock"> 
               <Setter Property="VerticalAlignment" Value="Center" /> 
               </Style> 
             </DataGridTextColumn.ElementStyle> 
            </DataGridTextColumn> 
             <DataGridTextColumn Binding="{Binding dueAmount, StringFormat={}{0:0.00}}" Width="172"> 
              <DataGridTextColumn.ElementStyle> 
              <Style TargetType="TextBlock"> 
               <Setter Property="HorizontalAlignment" Value="Right" /> 
               <Setter Property="VerticalAlignment" Value="Center" /> 
                <Setter Property="Margin" Value="0,0,60,0"/>              
               </Style> 
             </DataGridTextColumn.ElementStyle> 
            </DataGridTextColumn> 
           </DataGrid.Columns> 
          </DataGrid>

在這裏，我將我的PreviewKeyDown事件代碼

private void gridcancelled_PreviewKeyDown(object sender, KeyEventArgs e) 
    { 
     if (e.Key == Key.Up) 
     { 
      e.Handled = true; 
      if (gridcancelled.SelectedIndex == 0) 
      { 
       gridcancelled.SelectedIndex = gridcancelled.Items.Count - 1; 
      } 
      else 
      { 
       gridcancelled.SelectedIndex--; 
      } 
     } 
     if (e.Key == Key.Down) 
     { 
      e.Handled = true; 

      if (gridcancelled.Items.Count - 1 > gridcancelled.SelectedIndex) 
      { 
       gridcancelled.SelectedIndex++; 
      } 
      else if (gridcancelled.SelectedIndex == gridcancelled.Items.Count - 1) 
      { 
       gridcancelled.SelectedIndex = 0; 
      } 
     } 
    }

請給我你的建議。
在此先感謝。

給予你的數據網格代碼。我會編輯它。 –

感謝您的回覆@KyloRen請檢查我是否添加了示例代碼... – Sagar

您的意思是單元格聚焦時顯示的邊框？ – safi

更新：更改您的代碼如下：

private void gridcancelled_PreviewKeyDown(object sender, KeyEventArgs e) 
    { 
     if (e.Key == Key.Up) 
     {    
      if (gridcancelled.SelectedIndex == 0) 
      { 
       gridcancelled.SelectedIndex = gridcancelled.Items.Count - 1; 
       SetFocus(gridcancelled.SelectedIndex, gridcancelled.CurrentCell.Column.DisplayIndex);      
      } 
      else 
      { 
       gridcancelled.SelectedIndex--; 
      }     
     } 
     if (e.Key == Key.Down) 
     {     
      if (gridcancelled.Items.Count - 1 > gridcancelled.SelectedIndex) 
      { 
       gridcancelled.SelectedIndex++; 
      } 
      else if (gridcancelled.SelectedIndex == gridcancelled.Items.Count - 1) 
      { 
       gridcancelled.SelectedIndex = 0;     

       SetFocus(gridcancelled.SelectedIndex, gridcancelled.CurrentCell.Column.DisplayIndex); 
      }    
     } 
    } 

    public void SetFocus(int SelectedIndex,int SelectedCellIndex) 
    { 
     var row = gridcancelled.ItemContainerGenerator.ContainerFromIndex(SelectedIndex) as DataGridRow; 

     DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(row); 

     var cell = presenter.ItemContainerGenerator.ContainerFromIndex(SelectedCellIndex) as DataGridCell; 

     Keyboard.Focus(cell); 
    } 

    public T GetVisualChild<T>(Visual parent) where T : Visual 
    { 
     T child = default(T); 
     int numVisuals = VisualTreeHelper.GetChildrenCount(parent); 
     for (int i = 0; i < numVisuals; i++) 
     { 
      Visual v = (Visual)VisualTreeHelper.GetChild(parent, i); 
      child = v as T; 
      if (child == null) 
      { 
       child = GetVisualChild<T>(v); 
      } 
      if (child != null) 
      { 
       break; 
      } 
     } 
     return child; 
    }

現在GUI問題已解決......但KeyDown事件並未解僱@kylo Ren – Sagar

With Out使用KeyDown事件也它的工作正常......但在這裏我的問題是我想要做一些行動，當用戶選擇一個行，並點擊輸入關鍵字我需要做一些行動......所以我認爲它不可能與鍵盤事件這是爲什麼我有選擇了Preview_KeyDown事件@kylo Ren – Sagar

@sagar你有沒有移除PreviewKeyDown事件？ –

你的問題是FocusVisualStyle

<DataGrid.CellStyle> 
        <Style TargetType="DataGridCell"> 
         <Style.Triggers> 
          <Trigger Property="IsKeyboardFocusWithin" Value="True"> 
           <Setter Property="BorderBrush" Value="DarkTurquoise" /> 
           <Setter Property="IsSelected" Value="True"/> 
           <Setter Property="BorderThickness" Value="0"/> 
          </Trigger> 
         </Style.Triggers> 
         <Setter Property="FocusVisualStyle"> 
          <Setter.Value> 
           <Style> 
            <Setter Property="Control.Template"> 
             <Setter.Value> 
              <ControlTemplate> 
               <Rectangle Margin="-2" StrokeThickness="1" Stroke="Red"/> 
              </ControlTemplate> 
             </Setter.Value> 
            </Setter> 
           </Style> 
          </Setter.Value> 
         </Setter> 
        </Style> 
       </DataGrid.CellStyle>

對不起@safi仍然無法將焦點移動到導航的行。我想讓焦點集中到導航的行... – Sagar

@sagar give PreviewKeyDown事件代碼也是。如果你已經在那裏寫了任何代碼 –

Plz再次檢查我的代碼我已經添加了我的預覽keydown事件代碼@KyloRen – Sagar
