防止在WPF DataGrid中选择多行 [英] Prevent multiple row selection in WPF DataGrid

问题描述

我在WPF DataGrid中具有以下XAML标记：

I have the following XAML markup in a WPF DataGrid:

<DataGrid ItemsSource="{Binding ResultList}" Grid.ColumnSpan="4" Grid.Row="7" Height="150" 
          HorizontalAlignment="Left" Margin="10,0,0,0" Name="gvResults" 
          VerticalAlignment="Bottom" Width="590" AutoGenerateColumns="False" SelectionChanged="gvResults_SelectionChanged"
           SelectionUnit="FullRow">
    <DataGrid.Columns>
        <DataGridTextColumn IsReadOnly="True" Binding="{Binding Name}" Header="Name" ScrollViewer.VerticalScrollBarVisibility="Auto" Width="190" />
        <DataGridTextColumn IsReadOnly="True" Binding="{Binding Surname}" Header="Surname" Width="190" />
        <DataGridTextColumn IsReadOnly="True" Binding="{Binding Age}" Header="Age" Width="*" />
    </DataGrid.Columns>
</DataGrid>

是否可以防止用户在按住 Ctrl 键还是用鼠标选择多个行？

Is it possible to prevent users from selecting multiple rows while holding down the Ctrl key or selecting multiple rows with a mouse?

我在SelectionChanged事件中尝试了以下代码，但它不起作用：

I've tried the following code in the SelectionChanged event but it does not work:

private void gvResults_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (gvResults.SelectedItems.Count > 1)
    {
        e.Handled = true;
    }
}

推荐答案

尝试指定< DataGrid SelectionMode = Single
和可选的 SelectionUnit = FullRow

SelectionMode的可用选项为

The available options for SelectionMode are

• 单


• 扩展

，对于SelectionUnit是

and for SelectionUnit are

• Cell


• FullRow


• CellOrRowHeader
