Hi All,

I'm using the new Ajax Tooltip control (looks great BTW) and am having a small problem when turning on http compression using Blowery.  I'm using the latets blowery libs and the Promethius lib version - 2007.1.626.0. 

I get the common 'PageRequestManagerParserErrorException' which a very good post on your site identifies as a possible loss of MS Ajax Header information.

Has anyone else encountered this? Anyone have any suggestions (PS, I have tried turning off compression on the scriptResourceHandler element).

Thanks in advance

Guido Tapia

Hi Guido Tapia,
Another customer reported the same error in a different scenario - please review the forum thread. As we were able to reproduce it and I believe the problem is the same, I only need to make sure that you have the same situation. Are you using a RadToolTipManager and have you set the AjaxUpdate handler?

Kind regards,

Yes, Here is the aspx code:

<telerik:RadToolTipManager ID="rttm" runat="server"      OnAjaxUpdate="DisplayTooltipForCell" ManualClose="true" />

The DisplayTooltipForCell is a very simple piece of code very similar to your TolltipManager sample (on line demo) so I dont think it is relevant.

Thanks

Hello Guido Tapia,
Here is what we found out for the error when we use ASPRedirectory:

-------------------------------------------------------
After we researched the issue, we found out that it cannot be fixed by our developers here at Telerik - it turned out that it is generated by the MS Ajax framework. You can test this by using an UpdatePanel and a button inside it on a page with enabled ASPRedirectory:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">  
    <ContentTemplate> 
        <asp:Button ID="Button1" runat="server" Text="Test" />   
    </ContentTemplate> 
</asp:UpdatePanel> 

As you can see - you get the same error once you push the Button even though the page contains no Telerik controls. And as the Prometheus controls are built on top of ASP.NET AJAX, you get the error when you use them
-------------------------------------------------------

Could you please make the same test - in case you can reproduce the problem with the UpdatePanel and without any Telerik controls, then we cannot help.

Greetings,

I believe this has something to do with the Transfer-Encoding of the page being chunked and the client not knowing what to do with the compressed content.  If there's a way to check for the chunked encoding in the blowery code without having the call to app.Response.Headers throw an error, I think this could be subverted.
