I'm having an issue getting the selected item from the passed event, mostly because the demo uses "e.dataitem"

like this:

function onSelect(e) {
        if ("kendoConsole" in window) {
            var dataItem = e.dataItem;
            kendoConsole.log("event :: select (" + dataItem.Text + " : " + dataItem.Value + ")");
        }
    }
My attempt to recreate this failed, dataItem has no such members:


@(Html.Kendo().MultiSelect()
                              .Name("JobIds")
                              .HtmlAttributes(new { style = "Width:700px; height:60px; overflow-y:scroll;", aria_label = "editor" })
                              .DataTextField("job_name")
                              .DataValueField("job_id")
                              .HeaderTemplate("<div class=\"dropdown-header\">" +
                                        "<span style=\"width=350px\">Job Name</span>" +
                                        "<span style=\"width=350px\">Parent Name</span>" +
                                        "</div>\n <table>")
                              .ItemTemplate("<span class = \"namespan\">#: data.job_name #</span> <span class=\"parentspan\">#: data.job_parent #</span >")
                              .DataSource(source =>
                                {
                                    source.Read(read =>
                                    {
                                        read.Action("JobSearch", "SupportEditor");
                                    })
                                    .ServerFiltering(true);
                                })
                              .Events(e =>
                              {
                                  e.Select("Job_onSelect")
                                  })


function Job_onSelect (e) {
        var dataItem = e.dataItem;
        console.log("event :: select (" + dataItem.Text + " : " + dataItem.Value + ")");
    }


The console reads:


event :: select (undefined : undefined)


The only way i have managed to pull data is with direct reference to the multiselect like below:

function Job_onSelect(e) {
console.log($("#JobIds").data("kendoMultiSelect").value().toString());
}
But this does not provide the values of selected item value as it is selected; instead it only gives the full value of the multiselect before the change occurs (e.g. if 3 items are selected it only returns items 1 and 2, and when the first item is selected it returns nothing).

Hi Jody,

To display the data of the selected MultiSelect item, you need to change the marked below properties. The new values should be these defined in the DataTextField and DataValueField configuration of the component. In the context of the shared code, the below:

function Job_onSelect (e) {
        var dataItem = e.dataItem;
        console.log("event :: select (" + dataItem.Text + " : " + dataItem.Value + ")");
}

should be changed to:

function Job_onSelect (e) {
        var dataItem = e.dataItem;
        console.log("event :: select (" + dataItem.job_name+ " : " + dataItem.job_id+ ")");
}

Try the suggested above changes and let me know if they help you achieve the targeted functionality in your application.
