Over discussed problem: RadWindow page loads twice

[dorina]

Hello, yes, I know the problem is overdiscussed, but I tried all the workarounds proposed by you, still doesn't work for me..

I set ReloadOnShow = false, put the code do disable cash in PreRender handler :

Response.Cache.SetCacheability(

HttpCacheability.NoCache);
Response.Cache.SetNoServerCaching();
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");
Response.Expires = -1;
Response.CacheControl = "no-cache";

But the page still loads twice.

Hello dorina,

Please provide more details about your exact setup:

1. The declaration of the RadWindow / RadWindowManager that you are using
2. The code with which you are opening the RadWindow.

<input id="hdnShowNotification" runat="server" type="hidden" value="0" />

  

<telerik:RadWindowManager ID="RadWindowManager1" VisibleStatusbar="false"
runat="server" Skin="Default" EnableShadow="true" ShowContentDuringLoad="false"
ReloadOnShow="false">

<Windows>   

<telerik:RadWindow ID="notificationWindow" runat="server"
Behaviors="Close, Move, Resize"
NavigateUrl="CustomNotification.aspx" Width="630" Height="300"
Title="Notifications" Modal="false"
ShowContentDuringLoad="false" ReloadOnShow="false">  

</telerik:RadWindow>  

</Windows>  

</telerik:RadWindowManager>

  

<script type="text/javascript">  

  

// Attach a handler to the load event.

  

Sys.Application.add_load(clactivate);   

  

function clactivate(){    

    var showNotif = $get("<%= hdnShowNotification.ClientID %>");   

    if(showNotif != null && showNotif.value == "1")   

    {

        var WinId = "Win" + Math.random().toString();   

        var Url = "CustomNotification.aspx?wid=" + WinId;   

        var oManager = GetRadWindowManager();   

        var oWnd = oManager.GetWindowByName("notificationWindow");   

        if (oWnd){   

            oWnd.SetUrl(Url);   

            oWnd.Show();   

        }

    } 

} 

  

</script>

I set a hidden field a value ("1") in PageLoad event if I need to show the window :

if (!IsPostBack)
{
     //show notifications
     if (condition to show)
     {
         hdnShowNotification.Value = "1";
    }
}

Hello Dorina,

I tried to reproduce the problem, but everything worked as expected and the content page was not loaded twice (i.e. Page_Load was called only once). This leads me to believe that the problem is somewhere else, but to be able to help, I need to get a better view over your exact setup.
Please open a support ticket and send me a sample project that isolates the problem (this blog post will help you in this task) and I will check it right away.
