Product Telerik UI for ASP.NET Core
Progress Telerik UI for ASP.NET Core version Created with the 2023.1.117 version


How can I define my own custom HtmlHelper methods for an arbitrary Telerik UI for ASP.NET Core component?


To achieve the desired result:

  1. Create a static Extension Method to extend the desired type for the utilized configuration of the component.
  2. Within the method, implement the desired logic and return the extended type.
  3. From there, reference the extension method within the page in which it will be utilized.
  4. Finally, invoke the defined extension method inside the component's configuration.

The following example illustrates how to define a custom HtmlHelper method for the Grid:

    @using TelerikExample.Extensions

         .Columns(columns =>
             columns.Bound(p => p.Discontinued);
             columns.Bound(p => p.Approved);
         .DataSource(dataSource => dataSource
             .Read(read => read.Action("Orders_Read", "Grid"))
    namespace TelerikExample.Extensions
        public static class GridExtension
            public static GridBuilder<T> CustomPageable<T>(this GridBuilder<T> builder)
                where T : class // Custom method for reusing several configartion methods simulatenously.
                return builder
                    .Pageable(conf =>
