Hi, I've been trying to find a solution on my own for a few days without any resolve, so I'm hoping someone can help me out.   I can't seem to add any sort of AJAX web part to our sharepoint sites.  I've also done my best to rule out as many factors as possible, so the web part is strictly an update panel with no other code.  However, I have tried several other ajax web part tutorial .dll's with no change in success.

I've made the changes to the web.config file as noted in several places.  A few specific parts...here are the controls I've listed in the web.config file:

<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

<add tagPrefix="ajax" namespace="Microsoft.Web.UI" assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

<add tagPrefix="ajax" namespace="Microsoft.Web.UI.Controls" assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

<add tagPrefix="ajax" namespace="Microsoft.Web.Preview.UI" assembly="Microsoft.Web.Preview"/>

<add tagPrefix="ajax" namespace="Microsoft.Web.Preview.UI.Controls" assembly="Microsoft.Web.Preview"/>

I've tried adding the compiled and signed .dll to the GAC to have it fully trusted, added the following line to the default.master:

<asp:ScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server"></asp:ScriptManager>

However, I still get the following error when I attempt to add an ajax web part to a site:

hi,

  follow the link... and do all changes on webconfig file..

http://www.infinitetiers.com/ajax_config.html

make sure that u hav installed ajax ctrltoolkit.

for a simple ajax webpart u can download the code from MSDN..

hope it will help..

anupam....

Take a look at my article

http://www.koffeekoder.com/ArticleDetails.aspx?id=340_Creating_Ajax_Enabled_Webparts 

Anupam-

 Thanks for the link, I've double checked that all those changes are made to the web.config and default.master file, but I'm still unable to get AJAX web parts to import successfully...

hi try out this code if u hav done all setting well then this will surely execute...

 i've tried adding the code suggested in, and still get similar results.  maybe i should try asking this question this way...

 given that i've made the suggested changes to the web.config file, the default.master, and every AJAX enabled web part does not import successfully, would there be any other areas that could commonly be the source of prohibiting me from having AJAX enabled web parts added?

thanks again in advance,

one last note for when i add these web parts...

 i generall place the web part .dll file into the GAC, and the .webpart file into the \wpcatalog folder.  i am under the assumption that this is the bare requirements of adding a webpart, but perhaps i'm wrong...
 

I believe I've figured out the problem and why it's been happening, although I'm not entirely sure as to why it's happening. 

 I've been doing the development locally and then bringing the files to the Sharepoint server.  When I do bring the files such as the assemblies to the server, I do it over the network...ie, \\servername\c$\windows\assembly.  I drop them in, give the server an iisreset, and expect them to work.

 
However, there are some permission problems, because if I remote into the server, and look in the GAC, the files I've just put in are NOT there.  So I then have to bring the files in while remoting into the server....

 It's a strange problem that doesn't make sense to me, but hopefully explaining this will save someone else some trouble.  Thanks again to everyone for the help!
