DataGridTextColumn双击全选

Question

我有一个DataGridTextColumn，但当我单击输入单元格时，文本现在变为可编辑，但当我双击文本时，它不会选择所有文本(或仅选择当前单词)。

                    <DataGridTextColumn ClipboardContentBinding="{Binding Path=Name}" SortMemberPath="Name" 
                                        Header="Name" 
                                        Binding="{Binding Path=Name, Mode=TwoWay, UpdateSourceTrigger=Explicit}" CanUserReorder="True" CanUserSort="True" CanUserResize="True" Width="SizeToHeader" />

其中一种解决方案是为数据单元设置样式，为每个单元设置MouseDoubleClick事件。

<Window.Resources>
    <Style TargetType="DataGridCell">
        <EventSetter Event="MouseDoubleClick" Handler="CellDoubleClick"/>
    </Style>
</Window.Resources>

和背后的代码..。

    /// <summary>
    /// Select all text in DataGridCell on DoubleClick
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void CellDoubleClick(object sender, RoutedEventArgs e)
    {
        DataGridCell cell = null;
        TextBox textBox = null;

        cell = sender as DataGridCell;
        if (cell == null)
        {
            return;
        }

        textBox = cell.Content as TextBox;
        if (textBox == null)
        {
            return;
        }
        textBox.SelectAll();
    }
