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