On remote desktop, the following code causes the list items to appear grey for a few seconds while scrolling.

<ListView Margin="10" ItemsSource="{Binding Items}" ></ListView>

But for this code, scrolling works fine

<ScrollViewer  VerticalScrollMode="Enabled" VerticalScrollBarVisibility="Visible"  >
    <ItemsControl ItemsSource="{Binding Items}" > </ItemsControl>
</ScrollViewer>

In both cases, the Items are a collection of strings. This issue does not happen when its on local machine.

I tried to configure windows remote desktop group policy setting, but didn't have any effects. What changes need to be done to make scrolling smooth in remote desktop?

• The ListView is "heavier" and requires a higher frame rate for smoothness. "Virtualization" also comes into play (or the lack of it). The ScrollViewer doesn't do much work in terms of "scrolling content" (like a web browser). – Gerry Schmitz Commented Mar 26 at 0:03

As Gerry said in the comments, The ScrollViewer doesn't do much work in terms of "scrolling content" (like a web browser). ScrollViewer allows child elements unlimited space with auto-sized rows or columns. When a virtualized ItemsControl is placed in ScrollViewer, it takes enough room to display all of its items, which defeats UI virtualization.

ListView perform UI virtualization for you. The reason why you see grey behavior on the remote desktop may be that the hardware performance of the remote desktop is not enough. If you don't have many elements, you can use ScrollViewer. If the number is large， you can consider data virtualization, which display a limited number of elements each time in ListView.
