how do I update user profile property in SharePoint 2013

Question

We are using sp2013.

There is a custom user profile property with name: MyProperty (boolean).

The property cannot be edited by user.

I want to update the property value for current user on an application page on click of a button.

Since the property cannot be edited by user, should RWEP?

Answer 1

An easier approach is to allow the user to update the property and just hide the value from their edit page. Then you don't need RWEP. Just a thought.

Answer 2

Run with Elevated privileges runs the Code in System Account/App pool account. So you will have to make sure that App pool account has "Manage Profile Permission" rights to the User Profile Service. Follow below steps: Go to Central Admin-->Choose Application Management --> Manage Service Applications--> Select the User Profile Service Application (do not open the service application). Click Administrators in the ribbon on top -->Add the App pool account and set the Manage Profiles permission. See this blog for Granting permission to UPS.

 SPSecurity.RunWithElevatedPrivileges(delegate()
       {
        using (SPSite site = new SPSite("http://servername"))//change the hardcoded URL to suit your requirement
        {
            SPServiceContext serviceContext = SPServiceContext.GetContext(site);
            UserProfileManager userProfileMgr = new UserProfileManager(serviceContext);
            UserProfile user = userProfileMgr.GetUserProfile(@'domain\username');
            user["propertyName"]  = "newValue";
            user.Commit();


        }
    });
