Question

我在C＃/ WPF应用程序中使用了以下xaml代码。

我需要能够在那些文本块和文本框之后显示View1的内容。相反，View1的内容现在出现在StackPanel内容之后。我在这里想念的是什么？谢谢你的帮助。

我在这里想念的是什么？

请勿将ContentPresenter放入Grid？

事实是，没有好的Minimal, Complete and Verifiable code example，我们无法肯定地说出来。但根据你发布的内容，看起来你只是将控件放在XAML的错误位置。

即。布局应该是这样的：

<Grid Margin="5">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
    </Grid.RowDefinitions>

    <StackPanel Grid.Row="0"  HorizontalAlignment="Left" VerticalAlignment="Top" Orientation="Horizontal" Height="28" Width="auto" Margin="5,0,0,0">
        <!-- contents of StackPanel -->
    </StackPanel>

    <Grid Margin="5" Grid.Row="1" >
        <!-- contents of inner Grid -->
    </Grid>
    <ContentPresenter Content="{Binding CurrentViewModel}" Grid.Row="2">
        <ContentPresenter.Resources>
            <DataTemplate DataType="{x:Type ViewModel:VM1}">
                <Views:View1/>
            </DataTemplate>
            <DataTemplate DataType="{x:Type ViewModel:VM2">
                <Views:View2/>
            </DataTemplate>                  
        </ContentPresenter.Resources>
    </ContentPresenter>
</Grid>

以所需顺序在WPF中显示数据
