    Hi  Joel Grütter,

    Our investigations have shown that it would be technically possible and that it is possible to read out the group memberships of other users even as a read-only user.
    Currently this can be achieved via the following script.

    //jQuery.Deferred used to wait while it checking
    var deferrer = jQuery.Deferred();
    //Name of Group to check
    var groupName = "Group Name";
     
    var context = new SP.ClientContext.get_current();
    var web = context.get_web();
    //Use People or Group Field and take ID of user in it
    var user = web.get_siteUsers().getById([[UserFieldSingle.ID]]);
     
    context.load(user);
    var groups = user.get_groups();
    context.load(groups);
    context.executeQueryAsync(
             Function.createDelegate(null, loadUserGroupsSuccess),
             Function.createDelegate(null, loadUserGroupsFail)
    );
    function loadUserGroupsSuccess() {
            var gEnumerator = groups.getEnumerator();                        
            var belongstoSpecifiedgroup = false;
            while (gEnumerator.moveNext()) {
                var currGroup = gEnumerator.get_current();
                if (currGroup.get_title().toLowerCase() == groupName.toLocaleLowerCase()) {
                    belongstoSpecifiedgroup = true;
                    break;
                }
            }
     
    //Resolve deferred with value
    deferrer.resolve(belongstoSpecifiedgroup);
     
    }
     
    function loadUserGroupsFail(sender,args) {
    //reject deferred with error
      deferrer.reject(args.get_message());
    }
     
    return deferrer.promise();

    In order to include it as an easy-to-use function in our expressions, I must ask you, to add this as an idea and give your vote for it.

    Hi Matthias
    Thanks for your initial code, everything was fine with it, and i don't know where my error came from... So adapt the code a little in order to allow multiple Groups (array) and also check multiple Users.
    In combination with the Validation Expression of a field it now solves perfectly our use case. Thanks for your help!


    //jQuery.Deferred used to wait while it checking

    var deferrer = jQuery.Deferred();

    //Name of Group to check

    var groupName = ["group1","grop2","group3"];




    var context = new SP.ClientContext.get_current();

    var web = context.get_web();

    //Use People or Group Field and take ID of user in it

    var user = web.get_siteUsers().getById([[Signer.ID]]);

    var user2 =  web.get_siteUsers().getById([[Approver.ID]]);




    context.load(user);

    var groups = user.get_groups();

    context.load(groups);

    context.executeQueryAsync(

             Function.createDelegate(null, loadUserGroupsSuccess),

             Function.createDelegate(null, loadUserGroupsFail)

    );

    context.load(user2);

    var groups = user.get_groups();

    context.load(groups);

    context.executeQueryAsync(

             Function.createDelegate(null, loadUserGroupsSuccess),

             Function.createDelegate(null, loadUserGroupsFail)

    );

    function loadUserGroupsSuccess() {

            var gEnumerator = groups.getEnumerator();                        

            var belongstoSpecifiedgroup = false;

            while (gEnumerator.moveNext()) {

                var currGroup = gEnumerator.get_current();

                if (groupName.includes(currGroup.get_title().toLowerCase()) == true) {

                    belongstoSpecifiedgroup = true;

                    break;

                }

            }




    //Resolve deferred with value

    deferrer.resolve(belongstoSpecifiedgroup);

    }




    function loadUserGroupsFail(sender,args) {

    //reject deferred with error

      deferrer.reject(args.get_message());

    }




    return deferrer.promise();

    Hi Joel

    There is no built-in function or hidden functionality to check this so far.

    The technical possibility of this new function was in discussion in our development team and needs some more investigation.
    Since these functionality is all running in client context it's needed to check if these queries would work for all users... and some more research is needed before starting an implementation.

    You can expect further updates about this topic here.

    Hi Thanks for the workaround.
    I tried your code, but I'm always getting "undefined" as a result. I'm using it in the Visible Expression of a Command Bar Action. Any idea how to fix or where the problem could be?


    Also, I could not find this request in the Online Ideas section. Should I open it instead (i would find this very helpful)
