WPF中的滚动条无法正确显示并克服TabControl

Question

因此，当我创建一个新的滚动条时，选项卡将其获取。 但是，当我滚动时，它也会跳过应用程序菜单。 我似乎找不到解决方案，并且尝试了所有方法。

我的猜测是它也位于底座面板中，但是我不知道如何设置它，因为如果我添加了一个新的底座面板，它将说“属性Content设置了多次。”

在下面您可以看到代码：

                <UserControl Content="{Binding Content}" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
               </ScrollViewer>
            </DataTemplate>
            </TabControl.ContentTemplate>
        </TabControl>

</DockPanel>

我希望只显示标签页，但它会滚动所有屏幕。

显然，该错误是因为我试图向窗口窗体添加滚动条，该滚动条是从tabControl内部的<UserControl Content="{Binding Content}"调用的。 由于某种原因，他们彼此联系。 我通过将Scrollviewer添加到UserControl来修复它，它看起来像这样：

 `<UserControl x:Class="ContabilitateMainWPF.Controls.TestUserControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:ContabilitateMainWPF.Controls"
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300" SizeChanged="UserControl_SizeChanged">
    <ScrollViewer>
        <Grid x:Name="Grid">
            <Button x:Name="button" Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Margin="199,0,0,0"/>
            <Button x:Name="button_Copy" Content="Button" HorizontalAlignment="Left" Margin="141,91,0,0" VerticalAlignment="Top" Width="75"/>
            <Button x:Name="button_Copy1" Content="Button" HorizontalAlignment="Left" Margin="30,195,0,0" VerticalAlignment="Top" Width="75"/>
            <Button x:Name="button_Copy2" Content="Button" HorizontalAlignment="Left" Margin="199,261,0,0" VerticalAlignment="Top" Width="75"/>
            <Label x:Name="label1" Content="LabelTest" HorizontalAlignment="Left" Margin="62,127,0,0" VerticalAlignment="Top"/>
        </Grid>
    </ScrollViewer>
</UserControl>`

希望这对某人有帮助。
