WPF XAML WrapPanel ListBox items in a row
提问by zyjespox
I'm forced to ask for help, while I'm not able to figure it out by myself. I'm working on WPF-XAML desktop application, in which GUI is mostly generated dynamically.
我被迫寻求帮助，而我自己却无法弄清楚。我正在开发 WPF-XAML 桌面应用程序，其中 GUI 主要是动态生成的。
My query regards styling of WrapPanel with ListBox items.
我的查询是关于 WrapPanel 与 ListBox 项目的样式。
Please find a piece of code from my usercontrol (.xaml):
请从我的用户控件 (.xaml) 中找到一段代码：
<DockPanel x:Name="xResultPanel">
<ListView x:Name="bResultPanel" ItemsSource="{Binding ResultList, UpdateSourceTrigger=PropertyChanged}">
<ListView.ItemTemplate>
<DataTemplate>
<Expander Header="{Binding GroupName}" Style="{DynamicResource FeatureExpander2}">
<WrapPanel ItemWidth="140" Orientation="Horizontal">
<ListBox x:Name="ListOfTiles" ItemsSource="{Binding VideoSamples}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Width="120" Margin="10" HorizontalAlignment="Left">
<Image />
<TextBlock />
</StackPanel
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</WrapPanel>
</Expander>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</DockPanel>
Above code returns ListBox items presented not in a row, but each item in new line.I tried to set MinWidth, Width etc for WrapPanel and ListBox, but with no result.
上面的代码返回 ListBox 项目不是在一行中，而是在新行中的每个项目。我试图为 WrapPanel 和 ListBox 设置 MinWidth、Width 等，但没有结果。
Thanks in advance for all related tips how to force WrapPanel to fill it's content horizontally.
预先感谢所有相关提示如何强制 WrapPanel 水平填充其内容。

The problem is that your WrapPanelonly has a single child: The ListBox. This means that the layouting is done by the ItemsPaneltemplate of the ListBox.
问题是您WrapPanel只有一个孩子：ListBox. 这意味着，布点是由做ItemsPanel的模板ListBox。
Try this instead:
试试这个：
<Expander Header="{Binding GroupName}" Style="{DynamicResource FeatureExpander2}">
<ListBox x:Name="ListOfTiles" ItemsSource="{Binding VideoSamples}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Width="120" Margin="10" HorizontalAlignment="Left">
<Image />
<TextBlock />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
</Expander>
