I've been trying unsuccssfully to be able to click on a row within the radgrid to trigger a postback so that when a user hits the "browser back button" it would back up to the original state or in my case a panel that was hidden. It seems that the postback is still ajaxified somehow and when hitting the back button it goes back to far as if the row selection postback never occured so the browser is not seeing it in it's history.
So I'm trying to hide and show panels depending on what the user clicks upon (all on the same page) and I can hide and show all these panels and hit the browser back button at any time and it will bring me to the previously hidden panel, but if I select a row with the radgrid with the settings "EnablePostBackOnRowClick = true"
it just backs up a whole page OR crashes my browser completely...Any ideas on what's going on here??? I've tried with and without the

RadAjaxManager

telerik:RadGrid ID="rgdUsers" runat="server" HeaderStyle-HorizontalAlign="Center" Width="98%" Skin="OurSkin" EnableEmbeddedSkins="false"

So I was able to get the browser back button to work without using historypoints when clicking on the radgrid, but was only able to do so by creating a postback through javascript as the radgrid always seemed to ajaxify itself even turning off ajax. The browser backbutton issue that was crashing my browser each time was due to some strange issue with the radGrid not liking to be wrapped in a div tag so by redesigning and taking the radgrid out of the div it stopped crashing the browser. Now the problem became that hiding the radgrid on the postback and hitting the browser back button crashed the browser again and the only attribute it would take would be visibility:hidden which doesn't free up space, so I had to place it off the page to achieve my goal of hiding it from a viewer. Quite a nice mess such a simple task created with this control.
