Nothing is selected DropDownList but value is not blank

[Patrick Rioux]

Hi,

I have a DropDownList using a server-side paging and when I have nothing selected, the control still return a value.

.text() return blank (ok)
.value() return something even if I didn't select anything yet.  Very strange default behavior.
Any idea?

<script type="text/javascript">

function logSelected() {
var dropdownlist = $("#dropDownList").data("kendoDropDownList");
var txt = dropdownlist.text();
var val = dropdownlist.value();
     kendoConsole.log('[Selected Value:'+val+']'+' [Text:'+txt+']');
      }
    
    $(document).ready(function() {
    
 $("#dropDownList").kendoDropDownList({
            autoBind: false,
            dataTextField: "SalesrepName",
            dataValueField: "SalesrepId",
            change: function(){
    },
   filter: "contains",
  minLength: 1,
  template: $("#scriptTemplate").html(),
  columns: [{field:"SalesrepId",title:"Salesrep"},
                      {field:"SalesrepName",title:"Salesrep Name"}],
            dataSource: new kendo.data.DataSource({
                type: "odata",
                serverFiltering: true,
                serverPaging: true,
                pageSize: 20,
                transport: {
                    read: "csp/mediapool/public/dt.common.odata.RequestServer.cls?$select=SalesrepId,SalesrepName&$tablename=dt_common_ui_samples_data.Salesrep&$orderby=SalesrepName"
                }
            })
        });
});
</script>

Just find out that setting the value manually fix the issue but I think this is a bug.

<input id="dropDownList" style="width:300px" value=""/>

Hello Patrick,

 
I could not replicate the described issue. Check this jsFiddle demo and let me know if I am missing something.

I have the same issue. The DropDownList won't submit an empty value. This seems to be a common use to have an option label which has an empty value. Is there a way to make this work properly?

Please check out the following fiddle which illustrates the issue:
http://jsfiddle.net/pL4JA/1/

When "Select a value" is selected and you click the button -- the value of the dropdown should be empty not "Select a value".
