XAML代码：

<Window

x:Class="WpfApplication1.MainWindow"

Title="Window1"
Height="768" Width="1300" ResizeMode="NoResize">

 <UserControl>
   <Grid x:Name="LayoutRoot">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>

        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <Border BorderThickness="1" CornerRadius="4,4,4,4" BorderBrush="#FF8C8E94" Background="#8C208AB0" Margin="8,20.66,10,0" Height="51" VerticalAlignment="Top" TextElement.FontWeight="Bold" TextElement.FontFamily="Comic Sans MS" TextElement.FontSize="18" TextElement.Foreground="#FF000000" OpacityMask="{x:Null}" x:Name="TopTitleMenu"/>
        <Border BorderThickness="1"

    <Grid.Background>
        <LinearGradientBrush EndPoint="0.5,1" StartPoint="-0.072,-0.118">
            <GradientStop Color="#FF132734" Offset="0"/>
            <GradientStop Color="#FF072E42" Offset="1"/>
        </LinearGradientBrush>
    </Grid.Background>

        <TabControl>  </TabControl>

  </Grid>
 </UserControl>
</Window>

Answer 1

TabControl不是问题。问题是 <Grid.Background> ... </Grid.Background>

像这样设置Grid的属性必须在Gird控件的所有内容之前或之后发生。

只需将TabControl声明移到Grid.Background上方即可。

将TabControl放置在网格中会产生错误
