Hi,

I just updated from MVC1 to MVC2 and all ajax request where working fine and now I get this exception:

Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
 
Details: Error parsing near '
 
 
 
<!DOCTYPE html P'.

I've read that there is a bug with the Role Provider but I disabled it and it's still happening... very odd that from working I have now trouble in every component that uses this.

any ideas/thoughts? 

thank you 

regards,

jose

Hello Jose,

Can you try using ASP:UpdatePanel instead of RadAjax in your scenario? Let me know if the problem persists.

All the best,

Hi, 

thank you for the help! I'm getting the exact same error with UpdatePanel :S Is this a web.config problem? Did I forget to include anything? This happened after I updated from MVC 1 to MVC 2 ! I was long time planing the migration and after this the RadAjax stopped working! Any ideas? Thank you very much

regards,

jose

Hi Jose,

It seems that there is some incompatibility with the MS AJAX Framework and MVC2. I suggest that you check that in the public forums and find a resolution there. Once the page works with ASP:UpdatePanel, it will work with RadAjax as well.

Do I need to update the javascript files :

MicrosoftAjax.js
MicrosoftMvcAjax.js

?

I haven't done that.. they're still the same that I used for MVC1

I changed the files and it's still happening... is it then worth moving to MVC3? Are all the telerik components suported?

Hello Jose,

Basically, if you can run asp.net page, with ASP:ScriptManager and ASP:UpdatePanel in it for instance, under MVC3, you should be able to use our RadControls for ASP.NET AJAX as well. However I would suggest that you try our extensions provided especially for MVC. Find more information about them in the below resources:
http://demos.telerik.com/aspnet-mvc
http://www.telerik.com/products/aspnet-mvc.aspx

Ok thank you very much! But you have any idea how to fix the incompatibility from MS AJAX Framework and MVC2 ? I would rather stay with MVC2 from a while and then change! I don't want to rush and move to MVC3 right now! I've read a lot of forums but all sugest the Response.Write error which is not my case.

regards,

jose

Hello Jose,

I am afraid that the issue is a bit out of our scope.
However I would suggest that you make a simple asp.net page with ASP:UpdatePanel and some controls making ajax, for instance a button which updates a label text. Then make sure this scenario can be integrated in MVC2. If this works fine, then you can try adding one by one the functionalities of your current scenario and thus see what is causing the issue.

Kind regards,
Iana

HI,

as you told me I've tried starting a new project only the essential things and see if it works! To my surprise it is not working event in that scenario... what else can I do? I'm working with MVC.net 2 , .net framework 3.5 SP 1 and IIS 7.5 ! What could be wrong there? I've been looking for a lot of time and I need a suggestion before I go mad.

my request looks like this:

The only thing I find odd is that is sending:

X-AspNet-Version:4.0.30319

Shouldn't it be 3.5?

Sorry that was my mistake... for the test project I selected framework 4.0 instead of 3.5.

Here I attach my sample, I only added 

<form id="form1" runat="server">
         
        <!-- You need to add this ScriptManager -->
        <asp:ScriptManager ID="scriptMgr" runat="server" />
         
        <div>
            This example demonstrates the benefits of an UpdatePanel.
        </div>
        <br />
         
        <!-- Only this area is updated on PostBack -->
        <asp:UpdatePanel ID="updatePnl" runat="server">
            <ContentTemplate>
             
                <fieldset>
                <legend>Panel with random names</legend>
                <br />
                <asp:Button ID="Button1" runat="server"
                    Text="Generate random names"
                    Width="200px" />
                <br />
                <div style="height: 35px; padding-top: 5px; padding-bottom: 5px">
                 
                </div>
                <asp:Label Font-Bold=true ID="lblNames" runat="server" Text="">
                </asp:Label>
                <br />
                </fieldset>
                    
            </ContentTemplate>
        </asp:UpdatePanel>
        
    </form>

this to the index page the rest is default mvc project

Hello Jose,

I am afraid that finding a resolution to this issue is out of our scope. I suggest that you post this issue in the Microsoft MVC forums.

Have you got working ASP.NET AJAX component with MVC2? I'm starting to think it is not possible because MVC doesn't allow postbacks.. could you provide a working example? I feel like I'm losing my time. The only workaround I see is doing a ajax request using jquery and forget about the postback behaviour.

could you confirm this? 

regards,

jose

Hello Jose,

Indeed, with MVC I would suggest that you do everything on the client and avoid performing page postbacks/callbacks.
