Dynamically built rad grids need ajaxified and client side click event

[Josh]

So here's the scenario that I have:

I have a dashboard that has multiple radgrids in it.  These rad grids are one offs (in other words no update, delete, add).  I want to be able to let the users click on a row and redirect to a report page.  All of this works until I want to have each radgrid update every 5 seconds.  The calls are made from code behind. I thought about adding a ticker like the example here:

http://demos.telerik.com/aspnet-ajax/grid/examples/client/livedata/defaultcs.aspx

However this doesn't work because the data I am pulling is designed to work for an increasing number of rad grids so if the client decided they want to add another radgrid they can.  I use a lambda expression to parse the object from code behind.  Which isn't really possible to do from javascript and ajax (that I am aware of).  If I add the static classes this makes the display to brittle and will require maintenance more often than I wanted. 

So I decided to go with the update panel binding the ajaxmanager to the radgrid at instantiation of the radgrid.  Here's my current problem.  If I bind the update panel I need to assign an ID to reference the control.  If I pass in the control during instantiation then I have to create concrete NeedDataSource classes.  Is there any way to create n number of rad grids from code behind and then have the following abilities:

1.   Allow row clicked events
2.   update every interval

I keep getting i.get_postBackElement() is undefined. Here's a look at some of the code I have (that doesn't work):

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    </telerik:RadAjaxManager>

    <fieldset id="Facility" class="dashboardFieldsetDisplay">
        <legend>Facility Data</legend>
        <asp:Panel ID="FacilityGrids" runat="server" CssClass="dashboardGrid"></asp:Panel>

        <legend>Region Data</legend>
        <asp:Panel ID="RegionGrids" runat="server" CssClass="dashboardGrid"></asp:Panel>
    </fieldset>
    <div class="clearBoth"></div>

I figured it out, though I don't fully understand how it's working.

I commented out the problem code because it kept giving me an javascript error but I left the ticker in it in which I rebind each of the radgrids in my list of radgrids which has each of the radgrids on the page.  So it rebinds all of them on the Tick event.  It loads everything "real time".  No need for ajax and from the looks of it it only causes on full page refresh that I can see, and this still allows me to use the rowclick event without specifying an static ID.
