DevExpress gridview virtual scrolling

See more:

Hi Team,
I have a DevExpress gridview control. For this grid, I have enabled virtual scrolling by adding this setting

<Settings  VerticalScrollBarMode="Visible" VerticalScrollBarStyle="Virtual" />

The feature is well described [here]

My client has another windows desktop application. My web application runs under that desktop application.
On my local machine, my web app works just perfect. I even have created a sample winform application with browser control in it and run my web app under that browser. This too worked very well.
But when we try to run this web app under client's third party desktop app, the scrolling feature described in the above link does not work. User cannot scroll down for more records. Scrollbar is there , but for that page only. By scrolling down further user should load next bunch of records and move to the next page. Which does not happen.
I am not able to reproduce this issue.

Any help on this is appreciated.

Thanks,
Lok.
