After trying something different, the issues seems about the "pager style->mode->Slider", if I change the style to something else e.g "

NextPrevAndNumeric

", there would be no problem at all.

And I can provide a small demo about this bug, but with different result.
as I can not upload attachment, I just give a simple description. create a new webpage, drag an "UpdatePanel" to the page, and another RadGrid on the updatepanel enable paging, sorting and set the pager style mode to slider, assign datasource in the code behind, when you click page 2, everything disappeared on the second page. but if you change the "mode" to "NextPrevAndNumeric", it would be fine.
