StackPanel stop scrolling while over a Datagrid WPF

Question

I've been working on a dynamic StackPanel that implement multiple Controls which is in a ScrollViewer. The problem i am facing is that i can't scroll through my whole StackPanel when my mouse hits a DataGrid. I figured that it's because a DataGrid has a scrolling option itself. I want to know how to disable it. I prefer to create and change my controls programmatically. In the solution, i need to be able to modify the DataGrid and the DataGrid must not stop user from scrolling down and up.

<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>

EDIT:

Answer 1

EDIT: RESUMED: In order to make a ScrollViewer that is fluid with DataGrid in it, you need to add this function to it.

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);
}

EDIT : Found the solution. Check the code, below! The issue is that the datagrid doesn't scroll the scroll viewer. You get the mouse scroll event and scroll the scroll viewer.

XAML :

<Window x:Class="testscroll.MainWindow"
