[英]Prevent multiple row selection in WPF DataGrid
I have the following XAML markup in a WPF DataGrid: 我在WPF DataGrid中有以下XAML标记:
<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>
Is it possible to prevent users from selecting multiple rows while holding down the Ctrl key or selecting multiple rows with a mouse? 是否可以阻止用户在按住Ctrl键或用鼠标选择多行的同时选择多行?
I've tried the following code in the SelectionChanged event but it does not work: 我在SelectionChanged事件中尝试了以下代码,但它不起作用:
private void gvResults_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (gvResults.SelectedItems.Count > 1)
{
e.Handled = true;
}
}

and optionally SelectionUnit="FullRow"
尝试指定<DataGrid SelectionMode="Single"
并选择SelectionUnit="FullRow"
The available options for SelectionMode are SelectionMode的可用选项是
and for SelectionUnit are 而对于SelectionUnit则是
