StackPanel stop scrolling while over a Datagrid WPF
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.

EDIT:
Solution
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.
