WPF - adding user control to listbox
提问by Saket
I am trying to add a usercontrolto a ListBox.
我正在尝试将用户控件添加到ListBox。
My usercontrol contains a collection of basic elements like textbox and dropdowns, in a fashion so that it creates a row of elements.
我的用户控件包含一组基本元素，如文本框和下拉列表，以某种方式创建一行元素。
The code for ListBox in my main window is as -
我的主窗口中 ListBox 的代码是 -
<GroupBox FontWeight="SemiBold" Foreground="#FF0CAEF9" Name="gbAddProducts" Style="{x:Null}" Header="ADD PRODUCTS" HorizontalAlignment="Left" Margin="0,256,0,0" VerticalAlignment="Top" Width="990" Height="207">
<ListBox Name="lstboxAddProduct" ItemsSource="{Binding Path=AddNewProductRowViewModelList, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" BorderThickness="0" Margin="0,10,-2,23">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<ContentControl Content="{Binding AddNewProductRowViewModel}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<Validation.ErrorTemplate>
<ControlTemplate>
<StackPanel>
<AdornedElementPlaceholder x:Name="aepForError"/>
<ItemsControl ItemsSource="{Binding}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ErrorContent}" Foreground="White" Background="#DC000C" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</ControlTemplate>
</Validation.ErrorTemplate>
</ListBox>
</GroupBox>
Here AddNewProductRowViewModelListis my user control list containing 5 controls. The Problem that I see is that when I run the code, the screen has 5 rows, ie I can click on the area to figure out theer are 5 rows as that section gets highlighted. But they are not visible.
这里AddNewProductRowViewModelList是我的用户控件列表，包含 5 个控件。我看到的问题是，当我运行代码时，屏幕有 5 行，即我可以单击该区域以找出 5 行，因为该部分被突出显示。但它们是不可见的。
Could it be some 'bring to front' sort of issue.
可能是某种“带到前台”的问题。
Please advise.
请指教。
Thanks in advance.
提前致谢。

I would do it this way instead:
我会这样做：
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<ContentControl>
<local:AddNewProductRowView Datacontext="{Binding AddNewProductRowViewModel}"/>
</ContentControl>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
