Hi all,
   
        In my aspx page i have placed the 10 datagrid controls and 2 ddls.If any event fired in this page all grid prerender event is firing.Within the Panel i have placed the controls.using ajaxmanager to refresh the controls.How to avoid this unwanted prerender event firing?

Regards
Sangeetha

I am trying to use a loading panel for when I authenticate a user, but it does not display. It's driving me crazy. This is the first time I've used RadControls. Here is the code below. Any ideas what I'm missing. Thanks in advance. KB

I'm using RadGrid 2008.1.515.35 with an ArrayList as datasource and trying to make a hierarchical grid working with paging and virtual scrolling.
I've tried so hard by i couldn't make. First of all the paging is not presented. I'm sure that there is enough data to make pager visible but it is not.
This behaviour is strange because when i'm using 2008.1.414.35 version, the paging is shown. Below is the source code. Please what i'm doing wrong ?

Thanks in advance.

Best regards.
