Comment on HOWTO : Create a Site with a custom template through code and assign specific user security (User has no rights to create a site). by koenvosters

KS, you don’t need RunWithElevatedPrivileges to call webservices. To use Ajax you do need to modify your web.config to support it.
I suppose you are asking the question because you are experiencing the double hop issue?
You can call webservices by making use of DefaultCredentials
http://support.microsoft.com/kb/813834
Double hop is explained here

So you can either use the method described in the support or use Kerberos authentication.

Did this answer your question?

Koen,

Is it possible to execute Ajax code (ex. a web service call) in sharepoint with elevated privileges?

Thanks,

I’ve heard some rumours that Microsoft is developing Ribbon tooling for SharePoint 2010. Maybe it will be included in the RTM?

Yes, if that happens it means it can’t find your CheckValue column. Take into account that CheckValue is case sensitive :p
A good check would be to make sure that it is not null, but that was not the point of my post Glad you figured it out.

Thanks koenvosters!

I have tried debugging it and foundout that this line :
if (properties.AfterProperties["CheckValue"].ToString() == “dontadd”)
was throwing an exception :
System.NullReferenceException was unhandled by user code
Message=”Object reference not set to an instance of an object.”

I couldn’t find the reason of this exception but i uninstalled and build and deployed again, it worked for me.

Sahridhayan : I have tried this for both list and document Library..worked fine for me.
If in the feature.xml , the scope is given as ‘Web’ , you will find the eventhandler at site features level, if you give it as ‘Site’ , you will need to activate it from the sitecollection features page.

Hi,

I did not find the feature listed as you pointed out (because i have done this for a Document Library). Hope it is a different take?

But i tested like this it works.

1. i went to the document library, click “New” button for creating a new document.
2. Word opens, and i typed content, save-> prompt -> enter value “CheckValue” i give
“dontadd” it stops me from saving. If i give any other value i allows to save.
3. I went an uploading a document, it prompts, but does not stop, it allows to save for any value.
4. i edited the 1st document, in word, and saved, again prompts, this time no stopping!

bit confused.

any direction which step is lost?

thanks,
sahridhayan

1.Me too faced the same, but from VS it says successfully built, and deployed “Done!”

2.It does not list the event handler in SP. (basically it does not get published)

3.So i went on using this
http://www.wssdemo.com/Lists/Resources/DispForm.aspx?ID=731

4.just for deployment. Great Success!, no extra step, just point the location
and add the event handler, by giving your class name, sequence, type.

5.and the i used the inspector as mentioned above now it shows the event handled.
6.and then i tested the event handler work. it did work, but few clarifications will post separately.

Thank you for wonderful tool put to gether.
