Wpf XAML ListView项已启用_Wpf_Xaml_Listview_Isenabled - Fatal编程技术网

Wpf XAML ListView项已启用

Wpf XAML ListView项已启用,wpf,xaml,listview,isenabled,Wpf,Xaml,Listview,Isenabled,我有以下XAML: <Grid Grid.Row="3" Margin="8,8"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefi

我有以下XAML:

            <Grid Grid.Row="3" Margin="8,8">
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>

    <!-- Setting 'UsingItems' here -->
                <CheckBox Grid.Row="0"
                    IsChecked="{Binding Path=UsingItems}" 
                    Content="{Binding Path=IncludeItemsText}" />

                <!-- This works as expected -->
                <CheckBox Grid.Row="1"
                    IsEnabled="{Binding Path=UsingItems}"/>

                <!-- This doesn't! Even though the ListView becomes enabled the Items aren't and the Checkboxes are not checkable! -->
                <ListView Grid.Row="2" IsEnabled="{Binding Path=UsingItems}"
                    VerticalAlignment="Stretch"
                    ItemsSource="{Binding Path=SortedItems}">
                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <DockPanel>
                                <CheckBox
                                    IsChecked="{Binding Path=.IsSelected}"
                                    Margin="0,2" Click="CheckBox_Click" />
                                <TextBlock
                                    Text="{Binding Path=.Item.ItemDescription}"
                                    Margin="4,0,0,0" 
                                    VerticalAlignment="Top">
                                </TextBlock>
                            </DockPanel>
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>
            </Grid>

如果属性“UsingItems”=false,我想禁用ListView中的所有项UsingItems'是使用第0行中的复选框设置的,我已通过在第1行中设置一个虚拟复选框确认了这一点-IsEnabled属性已按预期设置

但是,当“UsingItems”=true时,即使ListView已启用(并且项“look”已启用),ListView项仍保持禁用状态

我曾假设IsEnabled属性会过滤掉树,但这里没有发生这种情况

我哪里做错了

谢谢

您是否在ViewModel类上实现了
INPC
,并在其setter上引发了
PropertyChanged
事件?我在小样本中对其进行了测试,效果良好。ListViewItems正在与ListView本身一起启用。谢谢-您可以单击listViewItem内的复选框吗?是的,我可以单击<代码>绑定对于内部复选框-
IsChecked=“{Binding Path=.IsSelected}”
谢谢,当我保存项目时,退出表单,然后重新编辑,ListViewItems可按预期编辑。。一定是我的初始化有问题,我还没弄明白:-/
