我想在任何其他控件中显示列表框所选项目（图像），但尺寸较大
我尝试使用两个列表框，并设置 IsSynchronizedWithCurrentItem="True" ，但它无效，请找到以下代码。

我尝试过** XmlDataProvider**，但在实际情况下，我会通过收集获得图像。 sholud我处理相同的解决方案，即使从集合

您需要将ListBox SelectedItem绑定到您希望以更大的尺寸显示SelectedItem的容器的内容。
以下是您尝试做的一个小例子。
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<!-- Image ListBox -->
<ListBox Name="imageListBox" Grid.Column="0"
ItemsSource="{Binding Source={StaticResource myXmlDataBase}, XPath=Item}">
<ListBox.ItemTemplate>
<DataTemplate>
<DockPanel>
<Image Width="150" Margin="5" x:Name="Myimage" Source="{Binding XPath=@Image}"></Image>
<TextBlock Text="{Binding XPath=@SNo}" HorizontalAlignment="Center" FontWeight="Normal" FontSize="13" />
</DockPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<!-- Selected Image -->
<ContentPresenter Grid.Column="1"
Content="{Binding ElementName=imageListBox, Path=SelectedItem}">
<ContentPresenter.ContentTemplate>
<DataTemplate>
<Image Source="{Binding XPath=@Image}"></Image>
</DataTemplate>
</ContentPresenter.ContentTemplate>
</ContentPresenter>
</Grid>

在您的代码中为列表框添加选择更改事件处理程序：
lv.SelectionChanged += lv_SelectionChanged;
private void lv_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
//Get selected item and do what you want with it here.
}
EDITS，想要在XAML中只能使用CollectionViewSource
<Window.Resources>
<CollectionViewSource x:Key="myViewSource" d:DesignSource="{d:DesignInstance {x:Type YOUR_DATA_TYPE}, CreateList=True}"/>
<CollectionViewSource x:Key="myPath_ViewSource" Source="{Binding Image, Source={StaticResource myViewSource}}"/>
</Window.Resources>
然后
<Grid DataContext="{StaticResource myViewSource}">
//SOME LIST BOUND TO MAIN CONTEXT
</Grid>
// LIST BOUND TO SELECTED PATH
<ListView
ItemsSource= "{Binding Source={StaticResource myPath_ViewSource} }" ...
当然，您需要在代码中获取myViewSource并填充数据
快速完成后，你需要自己修改并改进它，
