AJAX Extenders in SharePoint 2010

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :SharePoint
Hello All, I have few WebParts from 2007 and I am trying to deploy them in 2010.  None of the extenders seem to be working. Initially I got the error: "Message: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll." I added the tag: <cc1:ToolkitScriptManager id="ScriptManager" runat="server"></cc1:ToolkitScriptManager> it went away. Now I am seeing: Message: 'Sys' is undefined Message: 'Type' is undefined Message: 'Sys.Extended.UI' is null or not an object Message: Sys.ArgumentException: Value is not the name of the type being registered or the name is a reserved word.Parameter name: typeName Can you please help me.

ASP.NET AJAX UpdateProgres control in sharepoint 2010 Application pages ?


How to show the Update Progress status on an custom application page in sharepoint 2010 site. Any suggestions are most welcome

Basically we are getting a bunch of list items in the code behind of the application page & processing them, which will take atleast 10 seconds or more, so we would like to show a Update progress Control/image till the process is done. 

Can we use ASP.NET AJAX UpdateProgress control in sharepoint 2010 Application pages ? 

(We also prefer this process asynchronously, but the user has to indicate the list items to be processed, so Update progress control sounds like a good idea )

ClientAccessPolicy file in SharePoint 2010

I am upgrading my Silverlight demo code from the old beta to beta 2 and see that there are a few new considerations for the deployment of ClientAccessPolicy.xml files. In a previous post I demonstrated how to do this for SharePoint 2007. The heartburn that I get with that approach is any site collection owner or designer can drag the file into the site collection and open the site up to unwanted client access issues. In 2010 the virtual path provider no longer serves the files from the root of the site collection
