Question

我一直在研究一个动态StackPanel，它实现了ScrollViewer中的多个控件。我面临的问题是，当我的鼠标点击DataGrid时，我无法滚动浏览整个StackPanel。我认为这是因为DataGrid本身有一个滚动选项。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>

Answer 1

编辑：已恢复：为了使其中包含DataGrid的ScrollViewer流畅，您需要将此功能添加到其中。

DataGrid dgvAssy = new DataGrid();

dgv.VerticalScrollBarVisibility = ScrollBarVisibility.Disabled;

dgv.PreviewMouseWheel += DgvAssy_PreviewMouseWheel;


private void DgvAssy_PreviewMouseWheel(object sender, System.Windows.Input.MouseWheelEventArgs e)
{
     scrollviewer1.ScrollToVerticalOffset(scrollviewer1.VerticalOffset - e.Delta);
}

编辑：找到解决方案。检查下面的代码！问题是数据网格不滚动滚动查看器。您将获得鼠标滚动事件并滚动滚动查看器。
