Thanks!  🤝

Here is one solution that might help you in wpf.You need to put the panel in ScrollViewer

Code

<ScrollViewer x:Name="hfSV" HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Hidden">
                       <WrapPanel x:Name="pnlHF"/>
</ScrollViewer>

up scroll

Code

  var scrollViwer = POSUIHelper.GetScrollViewer(hfSV) as ScrollViewer;
  if (scrollViwer != null)
  {
     scrollViwer.ScrollToVerticalOffset(scrollViwer.VerticalOffset - 5);
  }

down scroll

Code

var scrollViwer = POSUIHelper.GetScrollViewer(hfSV) as ScrollViewer;
if (scrollViwer != null)
{
   scrollViwer.ScrollToVerticalOffset(scrollViwer.VerticalOffset + 5);
}

Code

   public static class POSUIHelper
   {
       public static DependencyObject GetScrollViewer(DependencyObject o)
       {
           if (o is ScrollViewer)
           { return o; }

           for (int i = 0; i < VisualTreeHelper.GetChildrenCount(o); i++)
           {
               var child = VisualTreeHelper.GetChild(o, i);

               var result = GetScrollViewer(child);
               if (result == null)
               {
                   continue;
               }
               else
               {
                   return result;
               }
           }
           return null;
       }

       public static T FindChild<T>(DependencyObject parent, string childName) where T : DependencyObject
       {
           if (parent == null) return null;

           T foundChild = null;

           int childrenCount = VisualTreeHelper.GetChildrenCount(parent);
           for (int i = 0; i < childrenCount; i++)
           {
               var child = VisualTreeHelper.GetChild(parent, i);
               T childType = child as T;
               if (childType == null)
               {
                   foundChild = FindChild<T>(child, childName);

                   if (foundChild != null) break;
               }
               else if (!string.IsNullOrEmpty(childName))
               {
                   var frameworkElement = child as FrameworkElement;
                   if (frameworkElement != null && frameworkElement.Name == childName)
                   {
                       foundChild = (T)child;
                       break;
                   }
               }
               else
               {
                   foundChild = (T)child;
                   break;
               }
           }

           return foundChild;
       }

       public static T FindVisualParent<T>(DependencyObject child) where T : DependencyObject
       {
           DependencyObject parentObject = VisualTreeHelper.GetParent(child);
           if (parentObject == null) return null;

           T parent = parentObject as T;
           if (parent != null)
           {
               return parent;
           }
           else
           {
               return FindVisualParent<T>(parentObject);
           }
       }
   }

And u can and ScrollChangedEventArgs to track VerticalOffset changes,and you can use this solution for horizontal scrolling.
