Hi, 
 Is possible to set selected values of the multiselect which are not part of the current multiselect client values:  currently, bounded data  of the multilist


When working  with datatasource  which is OData Service, not all data is brought to the client.(All the data is found on the server).  But we still need to mark the selected values of the
multilist. Part of them is not on the client currently

Thanks,

Hello Baha,

 
MultiSelect widget allows to select only items, which ara part of the DataSource's view. If you need to show selected items on initial load when widget is not bound yet, then you can use the following approach.

Hi

I am using the above example, however I need to track when an item is removed., I currently use the below code to track items which have been deleted from the multiselect.  This works fine for items added during a normal search, but if I have preloaded the selected values, it doesnt find them?

change: function (e) {
            var previous = this._savedOld;
            var current = this.value();
            var diff = [];
            if (previous) {
                diff = $(previous).not(current).get();
            }
            this._savedOld = current.slice(0);
            // diff has the elements removed do whatever you want...

            if (diff.length > 0) {
                var urltag = "../Dashboard.svc/TagsDelete?EventOrJobNo=" + gridRowToolTipJson.JobNo + "&Tag=" + diff[0];

                $.ajax({
                    // type: "POST",
                    type: "GET",
                    contentType: "application/json; charset=utf-8",
                    url: urltag,
                    dataType: "jsonp",
                    success: function (data, textStatus, xmlHttp) {


                    }
                });
            }
        },

Hello Tom,

 I tried a similar approach to yours which seems to work ok. Here is a live demo: http://jsbin.com/atoqox/1/edit
