Kendo dropdown too slow while datasource read...

[Suk]

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:

• http://demos.telerik.com/aspnet-mvc/dropdownlist/virtualization

You may learn more about the virtualization here:

• http://docs.telerik.com/kendo-ui/web/combobox/virtualization
