    We recently updated to the latest kendoUI 2015.1.429 and noticed a weird issue on the dropdownlist select event.  Here is the code:  

    @(Html.Kendo().DropDownListFor(m => m.Deficiency.correctionId)
       .HtmlAttributes(new { id = "Deficiency_correctionId" })
       .OptionLabel("-- Select Correction --")
       .Events(e => e.Select("onDeficiencyCorrectionDDLSelect").DataBound("CorrectionDDLDataBound"))
    function onDeficiencyCorrectionDDLSelect(e) {
            var correction = this.dataItem(e.item.index());

    When I set an OptionLabel and get the dataItem using e.item.index() in the select event, I get the previous data item in the list.  However, if I removed the index() and just use this.dataItem(e.item); then it works fine.  Also, in cases where I don't use the OptionLabel and in KendoComboBoxes are OK.  Has this changed since the last update?  I ask because we are doing this in many places and also noticed this usage on other posts in this forum as well.

    Hello Quynh,

    You are right - there is a change. In order to support grouping and virtualization, we decided to move the optionLabel outside the items list and place it as a static header on top of the popup element. Please refer to the following article for more information on this subject.
