我有一个 wpf 应用程序，其中有四个单选按钮。

我想根据正在检查的单选框更改列表视图的内容。

我已经定义了数据模板，但找不到将它们分配给单选框选中事件的列表视图的方法。以下是数据模板。

        <Window.Resources>

    <DataTemplate x:Key="OneTimeDataTemplate">

                    <ColumnDefinition Width="418*" />

您也可以使用触发器来执行此操作

 <Grid>
    <Grid.Resources>
        <Style x:Key="DynamicTemplateStyleList" TargetType="ListView">
            <Style.Triggers>
                <DataTrigger Binding="{Binding RelativeSource={RelativeSource 
                             AncestorType=UserControl}, 
                             Path=DataContext.IsMonthlyChecked}" Value="True">
                     <Setter Property="ItemTemplate" 
                             Value="{StaticResource MonthlyDataTemplate}"/>
                </DataTrigger>
                <DataTrigger Binding="{Binding RelativeSource={RelativeSource 
                             AncestorType=UserControl}, 
                             Path=DataContext.IsOneTimeChecked}" Value="True">
                     <Setter Property="ItemTemplate" 
                             Value="{StaticResource OneTimeDataTemplate}"/>
                </DataTrigger>
                <DataTrigger Binding="{Binding RelativeSource={RelativeSource 
                             AncestorType=UserControl}, 
                             Path=DataContext.IsWeeklyChecked}" Value="True">
                     <Setter Property="ItemTemplate" 
                             Value="{StaticResource WeeklyDataTemplate}"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </Grid.Resources>
    <ListView Name="list" Style="{StaticResource DynamicTemplateStyleList}"/>
</Grid>

您可以尝试该代码：

 <DockPanel>
    <StackPanel Orientation="Horizontal" DockPanel.Dock="Top">
        <RadioButton x:Name="OneTimeRadioButton" Content="OneTime" IsChecked="True" />
        <RadioButton x:Name="DailyRadioButton" Content="Daily" />
        <RadioButton x:Name="WeeklyRadioButton" Content="Weekly" />
        <RadioButton x:Name="MonthlyRadionButton" Content="Monthly" />
    </StackPanel>
    <ListView ItemsSource="{Binding Items}">
        <ListView.Resources>
            <Style TargetType="ListView">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding ElementName=OneTimeRadioButton, Path=IsChecked}" Value="True">
                        <Setter Property="ItemTemplate" Value="{StaticResource OneTimeDataTemplate}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding ElementName=DailyRadioButton, Path=IsChecked}" Value="True">
                        <Setter Property="ItemTemplate" Value="{StaticResource DailyDataTemplate}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding ElementName=WeeklyRadioButton, Path=IsChecked}" Value="True">
                        <Setter Property="ItemTemplate" Value="{StaticResource WeeklyDataTemplate}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding ElementName=MonthlyRadionButton, Path=IsChecked}" Value="True">
                        <Setter Property="ItemTemplate" Value="{StaticResource MonthlyDataTemplate}" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </ListView.Resources>
    </ListView>
</DockPanel>
