[英]Multiple selection with checkbox using Datagrid in WPF
我想知道如何使用DataGridCheckBoxColumn選擇多個行。
在這里,我只能選擇一行,但是如何選擇多項。
我的XAML如下:
<UserControl.Resources>
<Style x:Key="itemstyle" TargetType="{x:Type DataGridRow}">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="LightGoldenrodYellow" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlTextBrushKey}" Color="Black" />
</Style.Resources>
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="IsSelected" Value="{Binding Path=IsSelected, Mode=TwoWay}" />
<Style.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="ItemsControl.AlternationIndex" Value="1" />
<Condition Property="IsSelected" Value="False" />
<Condition Property="IsMouseOver" Value="False" />
</MultiTrigger.Conditions>
<Setter Property="Background" Value="#EEEEEEEE" />
</MultiTrigger>
</Style.Triggers>
</Style>
</UserControl.Resources>
<Grid Width="500" Height ="300">
<DataGrid ItemsSource="{Binding Path=Script}" HeadersVisibility="Column" SelectionMode="Single" AlternatingRowBackground="Gainsboro" Background="White" AutoGenerateColumns="False" ItemContainerStyle="{StaticResource itemstyle}" CanUserAddRows="True" GridLinesVisibility="None" Height="242" HorizontalAlignment="Left" HorizontalContentAlignment="Left" IsEnabled="True" IsReadOnly="True" Margin="10,14,0,44" Name="dgMain" RowHeight="23" VerticalAlignment="Center" VerticalContentAlignment="Center" Width="478" >
<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseDoubleClick">
<i:InvokeCommandAction Command="{Binding EditData}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
<DataGrid.Columns>
<DataGridCheckBoxColumn Binding="{Binding Path=IsSelected}" Header="Select" Width="50" />
<DataGridTextColumn Binding="{Binding Path=Script_Text}" Header="Script" Width="400" />
</DataGrid.Columns>
</DataGrid>
</Grid>
謝謝

SelectionMode="Extended"
或SelectionMode="Multiple"
將使您的DataGrid為多選

訣竅是使用如下所示的RowHeaderTemplate
<DataGrid ItemsSource="{Binding}">
<DataGrid.RowHeaderTemplate>
<DataTemplate>
<Grid>
<CheckBox IsChecked="{Binding Path=IsSelected, Mode=TwoWay,
RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type dg:DataGridRow}}}"/>
</Grid>
</DataTemplate>
