    I realize there is this weird bug happening whenever i use radajaxmanager together with radwindow.

    Here is the problem.

    whenever i click on the radgrid row, the following function fires :
    function show(sender, args){
        winIBRouteRF = $find("<%=winIBRouteRF.ClientID%>");        




    This works fine until i introduced RadAjaxManager. I couldn't find the reference to the window anymore.
    It keeps returning null. The solution to this is if i place the above function outisde of the form tag,
    just below </form>. I cannot place this function on the bottom page due to my project requirement.

    Actually, not only radwindow, but sometimes, other objects just cannot be found using $find. I have to use
    onclientload event in order to get the reference. But unfortunately for radwindow, this event doesn't exist.

    I've tried to place the function in Sys.Application.add_load but it doesn't help.

    Any suggestions?


    PS: I'm not using RadWindowManager, just RadWindow.

    Hi Dexter,

    This is a really strange behavior and I am not sure how to reproduce this. In order to be able to help we would need a small sample where we can observe it. I would advise that you make sure you are not trying to reference an object while it is disposed due to the AJAX request - the best way to do so is the Sys.Application.Load event but I am not sure exactly how you have tried to use it. I would also advise that you examine the following online demo that is very similar to your scenario (a RadWindow opened from a RadGrid and it is an ajaxified scenario): http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window. I also advise against placing a RadWindow in an update panel, ajaxifying a RadWindow should be done as explained in the following help article: http://www.telerik.com/help/aspnet-ajax/radwindow-ajaxifying.html. Please examine these resources and compare them with your scenario. If you are still unable to resolve the situation please post some more details on the setup you have.
