Question

我有这个XAML代码，它会抛出错误：

该属性＆＃39;内容＆＃39;设置不止一次。

这整个代码指出了同样的错误。非常感谢。

编辑：添加了窗口的XAML

您必须以下列方式修改代码：

<Window>
...
    <StackPanel>
        <Grid Background="White" Name="DocumentRoot">
        ...
        </Grid>
        <DockPanel Name="DockPanel_Menu" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="0">
        ...
        </DockPanel>
    </StackPanel>
</Window>

Window 只能有一个孩子，所以你必须在某个容器中嵌入 Grid 和 DockPanel ，例如 StackPanel ，另一个 DockPanel 等。

XAML DockPanel：属性内容设置多次
