DropDownList TagHelper Overview

The Telerik UI DropDownList TagHelper for ASP.NET Core is a server-side wrapper for the Kendo UI DropDownList widget.

The DropDownList displays a list of values and allows for a single selection from the list. The user input is restricted within the predefined options.

Initializing the DropDownList

The following example demonstrates how to define the DropDownList by using the DropDownList TagHelper.

    <kendo-dropdownlist name="products" filter="FilterType.StartsWith"></kendo-dropdownlist>

Basic Configuration

The DropDownList TagHelper configuration options are passed as attributes of the tag.


    @(Html.Kendo().DropDownList()
          .Name("products")
          .DataTextField("ProductName")
          .DataValueField("ProductID")
          .HtmlAttributes(new { style = "width:100%;" })
          .Filter(FilterType.Contains)
          .DataSource(source => source
              .Read(read => read.Action("GetProducts", "Home"))
          )
    )

    <kendo-dropdownlist name="products" filter="FilterType.Contains"
                        placeholder="Select product"
                        datatextfield="ProductName"
                        datavaluefield="ProductID"
                        style="width: 100%;">
        <datasource type="DataSourceTagHelperType.Custom">
            <transport>
                <read url="@Url.Action("GetProducts", "Home")" />
            </transport>
        </datasource>
    </kendo-dropdownlist>
