Question

我正在使用wpf中的MVVm开发一个应用程序。在这里，我必须将用户控件放在另一个用户控件上。

主用户控件将具有用于保存信息的UI元素。另外，我需要将用户控件放在我有列表视图的位置。我需要将数据填充到列表视图中。

XAML如下

<UserControl x:Class="SMTF.TestCaseView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<UserControl.Resources>
    <Style x:Key="SMToggle" TargetType="{x:Type ToggleButton}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ToggleButton}" >
                    <Border CornerRadius="3" Background="{TemplateBinding Background}">
                        <ContentPresenter Margin="3" 
                        HorizontalAlignment="Center" 
                        VerticalAlignment="Center"/>
                    </Border>

< StackPanel>

< views:ExceptionStrip DataContext="{Binding ExceptionViewModel}"/>
