RadTooltipManager not working with domain root, but does work with /default.aspx

[Richard]

Hi

I've been playing with the demo's and really like the AJAX kit so will be buying it once I get paid for my current job, but whilst using the trial version I have come across an error with the RadTooltipManager and would appreciate some help if anyone is able to please.

Basically it works fine everywhere on the site, apart from the home page, but to make it more confusing it doesn't work when loaded via http://www.domain.com/ but it does work when I add default.aspx so http://www.domain.com/default.aspx

The error I get is:

RadToolTipManager response error:
Exception=Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 405

I've also attached a screenshot of the error.

My code is:

I've just re-downloaded and re-installed the trial, to make sure it wasn't something to do with that.

Many thanks in advance.

Hi Richard,

I cannot see anything wrong with the provided code (related to the actual controls, I cannot say anything about the database calls). The error you are receiving is a generic one and is usually related to cross-domain scripting and security. I would suggest that you start, for example, from the following google search: http://www.google.com/search?q=ajax+error+405.

You can also try loading the user control dynamically in a regular update panel and see if the issue persists, as it may be something related to the way you get the data - a webservice or a method from the user control may not be working properly.

You can also try examining the domain of the page (document.domain) for both cases - when it works and when it doesn't. If, for example, in one of the cases you get www.domain and in the other just domain this would be a viable reason for such an error.

In the end, if you cannot determine where this issue originates I would advise that you stick with the configuration that works.

Thanks for the advice, appreciate it.

It seems that there's something ajax not working, as I'm finding that the onitemcommand for datagrids in standard updatepanels aren't working either, unless I call them using /default.aspx.

No idea what yet though.

Hi Richard,

It would seem that your machine/project is not configured properly to use AJAX.  I hope the following articles will help you in troubleshooting this issue:
http://www.telerik.com/help/aspnet-ajax/introduction-general-aspnetajax-info.html
http://www.telerik.com/help/aspnet-ajax/introduction-adding-radcontrols-prometheus-existing-application.html

What I would advise is that you uninstall the MS AJAX framework, restart your machine, install it again, restart again and see if the issue persists. You can also try creating a RadControlsWebSite instead of the regular WebSite in VS as it has the needed handlers.

There is also another possibility for AJAX issues - we have found that the AjaxControlToolkit assembly, when present in the site's Bin directory (it does not even need to be reference anywhere) overrides some of the default MS AJAX scripts, so if you have it you can also try deleting it to see if this helps.

Kind regards,
Marin

Thanks Marin, I was pretty sure I'm all setup fine, but I checked anyway and it appears I am.  Tried a new RadControls site as you suggested too.

Just tried using Fiddler2 and it appears the 405 is basically the below:

The HTTP verb POST used to access path '/' is not allowed.

I am using IIS6 and have wildcard mapping setup for URL rewriting purposes, so I wonder if this is part of the problem, although I don't see why it should be.  Do you know if there is a way I can set the post to /default.aspx instead of /? 

I've tried the below and different variations with / and ~/ in the Page_Load of my default.aspx.vb:

Page.Form.Action = "default.aspx"

But it didn't work :(

Just thought I'd let you all know I found a solution, I just added the following to my URL Rewriting rules:

<rewrite url="^(.*)/(\?.+)?$" to="$1/default.aspx$2" />
