分层数据与嵌套WPF列表视图绑定

本文介绍了分层数据与嵌套WPF列表视图绑定的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一些数据，有一个详细的表格。我希望数据是psented在ListView $ P $。我想，当你在原来的列表中选择一个项目的明细数据显示为一个嵌套的ListView。我似乎无法弄清楚如何获取数据绑定工作。

下面是我到目前为止，（问题是 {绑定路径= FK_History_HistoryItems} ）：

＆LT; ListView控件名称=lstHistory的ItemsSource ={绑定源= {的StaticResource历史}}的SelectionChanged =lstHistory_SelectionChanged＆GT;     ＆LT; ListView.View＆GT;         ＆LT; GridView控件＆GT;             ＆LT; GridViewColumn DisplayMemberBinding ={绑定路径=名称}标题=名称WIDTH =100/＆GT;             ＆LT; GridViewColumn DisplayMemberBinding ={绑定路径=说明}标题=说明WIDTH =150/＆GT;             ＆LT; GridViewColumn DisplayMemberBinding ={绑定路径=总，转换器= {的StaticResource moneyConvert}}标题=总WIDTH =100/＆GT;             ＆LT; GridViewColumn DisplayMemberBinding ={结合转换器= {的StaticResource categoryAggregate}}标题=分类WIDTH =100/＆GT;         ＆LT; / GridView的＆GT;     ＆LT; /ListView.View>     ＆LT; ListView.Resources＆GT;         ＆LT;风格的TargetType ={X：类型的ListViewItem}＆GT;             ＆LT; setter属性=模板＆GT;                 ＆LT; Setter.Value＆GT;                     ＆LT;的ControlTemplate的TargetType ={X：类型的ListViewItem}＆GT;                         ＆LT; BORDER＆GT;                             ＆LT; StackPanel的＆GT;                                 ＆LT; BORDER NAME =presenter                                         背景={TemplateBinding背景}                                         BorderBrush ={TemplateBinding BorderBrush}                                         了borderThickness ={TemplateBinding了borderThickness}                                         填充={TemplateBinding填充}＆GT;                                     ＆LT; GridViewRow presenter /＆GT;                                 ＆LT; /边框＆GT;                                 ＆LT; BORDER名称=细节能见度=坍塌保证金=5                                         BorderBrush =黑了borderThickness =2＆GT;                                     ＆LT; StackPanel的保证金=5＆GT;                                         ＆LT; ListView控件的ItemsSource ={绑定路径= FK_History_HistoryItems}＆GT;                                             ＆LT; ListView.View＆GT;                                                 ＆LT; GridView控件＆GT;                                                     ＆LT; GridViewColumn DisplayMemberBinding ={绑定路径= ammount的}标题=ammount的WIDTH =100/＆GT;                                                     ＆LT; GridViewColumn DisplayMemberBinding ={绑定路径=类别}标题=类别WIDTH =100/＆GT;                                                 ＆LT; / GridView的＆GT;                                             ＆LT; /ListView.View>                                         ＆LT; / ListView控件＆GT;                                     ＆LT; / StackPanel的＆GT;                                 ＆LT; /边框＆GT;                             ＆LT; / StackPanel的＆GT;                         ＆LT; /边框＆GT;                         ＆LT; ControlTemplate.Triggers＆GT;                             ＆LT;触发属性=IsSelectedVALUE =真＆GT;                                 ＆LT;二传手的TargetName =细节属性=能见度VALUE =可见/＆GT;                                 ＆LT;二传手的TargetName =presenter属性=背景VALUE =海军/＆GT;                                 ＆LT;二传手的TargetName =presenter属性=TextElement.ForegroundVALUE =白/＆GT;                             ＆LT; /触发＆GT;                         ＆LT; /ControlTemplate.Triggers>                     ＆LT; /控件模板＆GT;                 ＆LT; /Setter.Value>             ＆LT; /二传手＆GT;         ＆LT; /样式和GT;     ＆LT; /ListView.Resources> ＆LT; / ListView控件＆GT;

解决方案

如果我正确地理解你的问题，你需要绑定到原始列表的的SelectedItem：

＆LT; ListView控件的ItemsSource ={结合的ElementName = lstHistory，路径=的SelectedItem}＆GT;

，然后设置的DataTemplate /视图需要。如果你不希望使用的ElementName的结合，你也可以使用的RelativeSource，但我发现的ElementName更容易阅读和理解。

I have some data that has a detail table. I want the data to be presented in a ListView. I want the detail data to appear as a nested ListView when you select an item in the original list. I can't seem to figure out how to get the data binding to work.

Here's what I have so far, (the problem is the {Binding Path=FK_History_HistoryItems}):

<ListView Name="lstHistory" ItemsSource="{Binding Source={StaticResource History}}" SelectionChanged="lstHistory_SelectionChanged"> <ListView.View> <GridView> <GridViewColumn DisplayMemberBinding="{Binding Path=Name}" Header="Name" Width="100" /> <GridViewColumn DisplayMemberBinding="{Binding Path=Description}" Header="Description" Width="150" /> <GridViewColumn DisplayMemberBinding="{Binding Path=Total, Converter={StaticResource moneyConvert}}" Header="Total" Width="100" /> <GridViewColumn DisplayMemberBinding="{Binding Converter={StaticResource categoryAggregate}}" Header="Categories" Width="100" /> </GridView> </ListView.View> <ListView.Resources> <Style TargetType="{x:Type ListViewItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ListViewItem}"> <Border> <StackPanel> <Border Name="presenter" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="{TemplateBinding Padding}"> <GridViewRowPresenter /> </Border> <Border Name="details" Visibility="Collapsed" Margin="5" BorderBrush="Black" BorderThickness="2"> <StackPanel Margin="5"> <ListView ItemsSource="{Binding Path=FK_History_HistoryItems}"> <ListView.View> <GridView> <GridViewColumn DisplayMemberBinding="{Binding Path=Ammount}" Header="Ammount" Width="100" /> <GridViewColumn DisplayMemberBinding="{Binding Path=Category}" Header="Category" Width="100" /> </GridView> </ListView.View> </ListView> </StackPanel> </Border> </StackPanel> </Border> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="details" Property="Visibility" Value="Visible" /> <Setter TargetName="presenter" Property="Background" Value="Navy"/> <Setter TargetName="presenter" Property="TextElement.Foreground" Value="White" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </ListView.Resources> </ListView>

解决方案

If I understand your question correctly you need to bind to the SelectedItem of the original list:

<ListView ItemsSource="{Binding ElementName=lstHistory, Path=SelectedItem}">

And then set the datatemplate/view as needed. If you don't want to use ElementName for the binding you could also use RelativeSource but I find ElementName is easier to read and understand.
