Getting access denied error while updating list items

I was getting access denied error while updating list items, I already tried to put my code into SPSecurity.RunWithElevatedPrivileges delegate, still I was getting error. Below was my actual code.

CODE:

//code line for updating list columns

Listitem.update()

List.Update()

After doing debugging and removing line by line from actual code I have figured out actual problem – the user who has contributor rights(normal user) was getting access denied error, admin users can able to update list without any problem, it’s because of LIST.UPDATE() statement, because contributor rights users don’t have permission to change anything into List settings, they can add/delete list items but they can’t able to change anything into list, after removing LIST.UPDATE() statement from my actual code, all users were able to successfully update the list items.

Enjoy!

How to find GUID of SharePoint list

Till now I came across many articles related to finding GUID of SharePoint list from SharePoint interface/GUI, but I think, below is easiest way to find GUID of list.

Go to respective List – >Click on Settings Menu – > Click on List Settings Link- > here in this list settings page, we can find many links, we need to click on “Audience targeting settings” link.

Now, currently we are in Audience targeting page, look up at the URL of current audience target page, that the current address have GUID of list, at the end of URL we can find GUID, like ?List={552bef05-b62c-4c76-a217-35e85a1507f1}
