    My kendo DropdownList is too slow while returning a list of 37,000 and more items...

       @(Html.Kendo().DropDownList()
                                .Name("NameList")
                                .DataTextField("Filter1")
                                .DataValueField("Filter1")
                                .HtmlAttributes(new { style = "font-family:Verdana; font-size:small" })
            
                                .AutoBind(false)
                                .DataSource(source =>
                                {
                                    source.Read(read =>
                                    {
                                        read.Action("GetFilterValues", "Home").Data("ParametersForNamesList");
                                    })
                                .ServerFiltering(true);
                                })
                            )

    functionParametersForNamesList() {
            return {
                text: "",
                selectedOption: "Name"
            };
        }

    Hi Suk,

    Please download the latest internal build and configure the DropDownList to use serverPaging and virtualization. See the following demo page:
    You may learn more about the virtualization here:
