【问题描述】：
我一直在开发一个动态 StackPanel，它实现了 ScrollViewer 中的多个控件。我面临的问题是，当我的鼠标碰到 DataGrid 时，我无法滚动整个 StackPanel。我认为这是因为 DataGrid 本身具有滚动选项。我想知道如何禁用它。我更喜欢以编程方式创建和更改我的控件。在解决方案中，我需要能够修改 DataGrid，并且 DataGrid 不能阻止用户向下和向上滚动。
<Window x:Class="testscroll.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:testscroll"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ScrollViewer HorizontalAlignment="Left" Height="300" Margin="10,10,0,0"VerticalAlignment="Top" Width="497">
<StackPanel x:Name="panel" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" />
</ScrollViewer>
</Grid>
这是我的测试代码

【问题讨论】：
-
您一定跳过了 WPF 第 1 课；使用 XAML 创建视图
-
为什么没有 XAML。如果您在编译期间生成它，XAML 更易于编写和查看。
-
因为 StackPanel 会随着用户输入值或更改选择而发生变化，所以面板的某些部分会被删除，而其他部分会被添加，这使得无法在 XAML 中对其进行编码。
