Hello;
As an end user when visiting the web page the scrolling vertically of the page is not smooth. It flickers and jumps back.
When I open Fiddler or Firebug and look at the HTTP requests there is are constant posts from the RadScriptManager about every second. I think this causes the scrolling issue.
I think the cause is a timer_tick for a clock that is causing the scrolling issue.
What are some ideas to resolve this issue and allow scrolling to work normally?
Thank you;

Hi,

RadScriptManager is not performing such requests so would you please share which other controls are you using on the page so we could be more helpful?

Hi Catto,
As Plamen said, this is not really caused by RadScriptManager. However, I understand that you have a timer on the page doing AJAX postbacks every second. As you suspect, these are no doubt what's causing the jerky scrolling. One approach would be to disable the feature that causes the scroll position to change during a postback, as described in this post: http://www.telerik.com/community/forums/aspnet-ajax/ajax/how-do-you-prevent-browser-scrolling-after-ajax-postback.aspx

// Prevent MS Ajax from changing scroll position after ajax postback. function scrollTo(x,y) {}
