【问题描述】:
我希望 ListBox 的 DataTemplate 具有 ItemsSource 作为边框集合。在每个边框内,我想显示另一个列表框,其中包含一组具有自己的 ItemsSource 的项目。 但是,当我尝试实现这种结构时,我无法填充任何数据。
我的 XAML 代码 -
<Grid x:Name="RightPanel" Grid.Column="2" Background="Beige">
<Border BorderBrush="Black" Margin="4" BorderThickness="1.5">
<ScrollViewer Margin="2" Focusable="False">
<ListBox x:Name="MainRightListBox" ItemsSource="{Binding ListBoxCollection,Mode=TwoWay}">
<ListBox.ItemTemplate>
<DataTemplate>
<ListBox x:Name="ChildListBox" ItemsSource="{Binding CurrentPage.ClonedVectorImages,Mode=TwoWay}" SelectedItem="{Binding ImageVectorSelected}" BorderBrush="Transparent" Background="Transparent">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel x:Name="canvas" Background="Transparent" Orientation="Horizontal" Tag="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}, Mode=FindAncestor}}">
<StackPanel.ContextMenu>
<ContextMenu>
<MenuItem Header="Delete" CommandParameter="{Binding}"
Command="{Binding PlacementTarget.Tag.DataContext.DeleteCloneCommand, RelativeSource={RelativeSource AncestorType={x:Type ContextMenu}, Mode=FindAncestor}}"/>
</ContextMenu>
</StackPanel.ContextMenu>
<Viewbox Width="35" Height="35" >
<Canvas Width="35" Height="35">
<Canvas>
<Path Fill="#ffda2526" Data="F1 M 0.000,112.500 C 0.000,50.369 50.368,0.000 112.500,0.000 C 174.632,0.000 225.000,50.369 225.000,112.500 C 225.000,174.633 174.632,225.000 112.500,225.000 C 50.368,225.000 0.000,174.633 0.000,112.500 Z" Height="30.667" Stretch="Fill" Width="31"/>
<TextBlock x:Name="tb1" Text="{Binding CountId}" Foreground="WhiteSmoke" FontSize="20" FontFamily="Arial Bold" Height="20" RenderTransformOrigin="1.588,1.224" Canvas.Left="9.322" Canvas.Top="3.335"></TextBlock>
</Canvas>
</Canvas>
</Viewbox>
<TextBox Text="Enter Text Here" Height="20" VerticalAlignment="Center"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</ScrollViewer>
</Border>
</Grid>
