What object type are selected items?

[Jason]

I used the MVC example which works perfect as-is I rewrote to work with a JSON request and it ALSO works fine, however when I try to view the data in a string it is trying to display the OBJECT and not the data inside the object. I ASSUMED that the SelectedData is also in JSON format becuase the MultiSelect datasourse is a JSON object.  

 

@(Html.Kendo().MultiSelect()

         .Name("GridSelect")         

         .AutoClose(false)

         .Placeholder("Select Which Grids to Print...") 

         .DataTextField("MapName")

         .DataValueField("Pagenumber")

         .DataSource(source =>

                     {

                         source.Read(read =>

                         {

                             read.Action("GetCascadeGrid100", "GridPrint")

                             .Data("filterGrid100");

                         })

                         .ServerFiltering(true);

                     })       

   )

 

 

So my issue is when I create click button function and I want to display the selected items..  here is what I have tried and the results.  I just want to display my data in a string   Mapname:1 PageNumber:234, Mapname:3, PageNumber:3244 etc...  

 

$(document).ready(function () {

            var Gridselect = $("#GridSelect").data("kendoMultiSelect");




            $("#get").click(function () {

              alert( Gridselect.value + ",  "  + Gridselect.text + ",");
  // this displays nothing but the commas

// Also have tried

               var output = '';
                for (var entry in Gridselect) {
                    output += 'key: ' + entry + ' | value: ' + Gridselect[entry] + '\n';
                }

                alert(output);
// This displays a bunch of data but none of my values, it seems to parse the PageNumber and the MapName so there is something in there.

// Also Tried

            alert(Gridselect.toSource);


            });
});

I noticed a stupid syntax error on the DataValueField it should have been PageNumber, so I am getting the Gridselect.value to display, however if I try to call the Gridselect.text I get an error saying text is not a function.

I'm getting closer..  this gets me all the VALUES but only One of the Text Items

alert("value: " + Gridselect.value() + "\n" + "text: " + Gridselect.dataItem().MapName); 

 

So my results looks something like this:

Value:123,343,456,654,754

text: Map1

 

I should have Map1, Map2, Map3, Map4, Map5

Hello Jason,

As documented in the following help topic, the dataItems method will return a collection with the selected data items, so you need to traverse all items in that collection for retrieving the MapName values:

Hope this helps.
