Question

我想要的功能DataGrid

1）列标题应居中对齐。

2）细胞值应保持对齐。

3）单击单元格上的编辑。

为了使标题居中对齐，我为列设置了HeaderStyle。因此，我必须将单元格内容设置为显式左对齐。

我使用以下代码处理单击编辑 -

 <DataGrid SelectionUnit="CellOrRowHeader">
   <DataGrid.Resources>
            <Style TargetType="{x:Type DataGridCell}">
                <EventSetter Event="PreviewMouseLeftButtonDown" Handler="DataGridCell_PreviewMouseLeftButtonDown"/>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type DataGridCell}">
                            <Grid Background="{TemplateBinding Background}">
                                <ContentPresenter HorizontalAlignment="Left" VerticalAlignment="Center"/>
                            </Grid>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
      </DataGrid.Resources>
      <DataGrid.Columns>
            <DataGridTextColumn Header="Expressions" Width="*" Binding="{Binding Path=., Mode=TwoWay}">
                <DataGridTextColumn.HeaderStyle>

                    <Style TargetType="DataGridColumnHeader">
                        <Setter Property="HorizontalContentAlignment" Value="Center" />
                    </Style>
                </DataGridTextColumn.HeaderStyle>
            </DataGridTextColumn>
        </DataGrid.Columns>
  </DataGrid>


 private void DataGridCell_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
  {
     DataGridCell cell = sender as DataGridCell;
     if (!cell.IsFocused)
     {
        cell.Focus();
     }
     if (cell != null && !cell.IsEditing && !cell.IsReadOnly)
     {

        DataGrid dataGrid = FindVisualParent<DataGrid>(cell);
        if (dataGrid != null)
        {
           if (dataGrid.SelectionUnit != DataGridSelectionUnit.FullRow)
           {
              if (!cell.IsSelected)
                 cell.IsSelected = true;
           }
           else
           {
              DataGridRow row = FindVisualParent<DataGridRow>(cell);
              if (row != null && !row.IsSelected)
              {
                 row.IsSelected = true;
              }
           }
        }
     }
  }

当我点击单元格时，它看起来像这样 - the wisdom on the net

我认为选择了TextBlock，编辑元素TextBox处于编辑模式。如何删除文本周围的蓝色？

在DataGrid中单击编辑时选择单元格的TextBlock
