Question

In my web application I use jquery dialogs to open popups.
The function used to perform this task is this:

function OpenPopup(popupTarget, width, height, params, onOpenFunction, onCloseFunction, popupElement){

// some code to parse the parameters
//`popupElement` is a div with `style="display: none;"`
// included in a master page which every page inherits from

    $(popupElement).dialog(
{
    autoOpen: false,
    resizable: false,
    height: height,
    width: width,
    modal: true,
    open: onOpenFunction,
    closeOnEscape: false,
    close: function (e)
    {
        var popupResult = $(this).dialog("option", "notification");

        $(this).dialog("destroy");

        if (!isHTMLElement)
            popupFrame.css("visibility", "hidden");

        if (jQuery.isFunction(onCloseFunction))
        {
            var funct = eval(onCloseFunction);
            funct(popupResult);
        }
    }
});

$(popupElement).dialog("open");
}

This is the function that calls the above method:

function FiltroNotifiche(){
params = "";

OpenPopup("~/manage/Popup/FiltroNotifiche.aspx", 450, 350, params, function (e) { }, function (strNotification)
{
    OnPopupReturn(true, strNotification, function ()
    {
        __doPostBack('UpdatePanel', 'Filtro=true');
    });
});
}

function OnPopupReturn(bRefresh, strNotification, senderFunction){
// this function parses strNotification and if, successful, calls:
    var funct = eval(senderFunction);
    funct();

}

Inside the popup I use the ICallbackEventHandlercallback interface.

The problem is that after opening and closing the popup (I can see the callback being executed and all), whatever I do next I’m getting kicked out, most likely because the session has expired.

A strange thing that I noticed is that this happens only if I get to the page that opens the popup (GestioneNotifiche.aspx) via the menu control, because if I get to there through a button PostBackUrl in another page, this doesn’t happen, and the session lives happily!

The menu has an xml data source and these bindings:

<DataBindings>
  <asp:MenuItemBinding DataMember="Menu" TextField="Text" Selectable="false" />
  <asp:MenuItemBinding DataMember="MenuItem" NavigateUrlField="NavigateUrl" TextField="Text" ValueField="Value" />
</DataBindings>

This is the menu item:

<MenuItem Value="" Text="Gestione notifiche" NavigateUrl="~/manage/GestioneNotifiche/GestioneNotifiche.aspx" />

I did notice the call through the menu has Request.HttpMethod = "GET", while via postback it is (rather obviously) "POST". Could this be the significant? I don’t really know much about the difference between GET and POST.

Thank you

Sounds like your problem is that authentication is being cleared and not your session. Check your page_load event to see if you are doing anything differently between a GET and POST request that would result in clearing the authentication.
