We are using the telerik controls in our web application. We have a page with panelbar and ajax manager for postbacks since user does not want to see the page post back.
We have totally 8 tabs. In each tab we have one rad grid. and in the tab 7 we have one grid with 7 columns(3labels and 4 textboxes item template).
We initially had pagination in all grids but the user does not want to use the pagination and required scrolling. So we disabled the paging and enabled the scrolling. Everything works fine in IE 10, Firefox, Chrome.
But some users using IE8 and xp. Here is the problem starts. When they open tab7, the AJAX loader starts but in few seconds the IE shows message "not responding". After a long time, the process is completing. And further ajax request are also not responding and taking so long time. This is happening only in IE8.
We investigate further and created a seperate page and had only that grid without ajax. This page is opening faster as expected. But when we add ajax and panel bar that is the time problem starts.
Note: When we add paging to the grid (20rows) everything works fine
Because of this issue, we have forced to postpone our production release.
Can any one of the Telerik employee help us to fix this problem?
