DropDownList in Razor Pages

Razor Pages is an alternative to the MVC pattern that makes page-focused coding easier and more productive. This approach consists of a cshtml file and a cshtml.cs file (by design, the two files have the same name).

You can seamlessly integrate the Telerik UI DropDownList for ASP.NET Core in Razor Pages applications.

This article describes how to configure the DropDownList component in a Razor Pages scenario.

For the complete project, refer to the DropDownList in Razor Pages example.

In order to set up the DropDownList component bindings, you need to configure the Read method of its DataSource instance. The URL in this method should refer the name of the method in the PageModel. In this method, you can also pass additional parameters, such as filter string and antiforgery token (see dataFunction).

    @inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf

            .HtmlAttributes(new { style = "width:300px;" })
            .DataSource(ds => ds
                .Transport(transport => transport
                    .Read(read => read

<kendo-dropdownlist name="products"
    <datasource server-filtering="true">
            <read url="@Url("/DropDownList/DropDownListCrudOps?handler=Read")" data="dataFunction" />
        function dataFunction() {
            var value = $("#products").getKendoDropDownList().filterInput.val();
            return {
                __RequestVerificationToken: kendo.antiForgeryTokens().__RequestVerificationToken,
                filterValue: value
   public JsonResult OnGetRead(string filterValue)
            if (filterValue != null)
                //orders is the DBContext
                var filteredData = orders.Where(p => p.ShipName.Contains(filterValue)); 
                return new JsonResult(filteredData);
            return new JsonResult(orders);
