Get item URL from SharePoint ItemAdding Event receiver

Question

I have a sharepoint list with the folders option enabled. My goal is to save the items only inside the folders so that I could grant unique permissions on the folder rather than the item itself.

In the ItemAdding event receiver I want to check whether the user is trying to create the item inside a specific folder(in which case I'll just return from the receiver) or the user is trying to add the item in the root of the list(in which case I'll cancel the event).

I can't seem to find a way to retrieve the item's full Url. I've tried properties.AfterUl, HTTPContext/SPContext saved in the constructor,etc.

Any idea would be greatly appreciated.

Basically, I want a similar functionality as in this post, but for a list instead of a document library:

Many thanks, Adrian

Answer 1

This should get the folder itself

string itemFolder = properties.Web.GetFolder(properties.AfterUrl);

After that you should be able to get all the properties of an object type SPFolder including Url.

For Folder URL directly:

string itemFolderUrl = properties.Web.GetFolder(properties.AfterUrl).Url;

I eventually managed to get the path using the referralurl from the httpcontext, however it doesn't work when using the quick edit.

Anyways, I found a better solution to fulfill my requirements: grant my users readonly permissions on the list and develop a custom action that uses elevated privilleges to create the folder and grant the necessary permissions.
