Description

What is the best approach to using Async/Await in the Telerik UI for ASP.NET Core Grid's action methods?

Solution

Kendo.Mvc.Extensions contains QueryableExtensions which include the ToDatasourceResultAsync method for asynchronous programming. The following contains the action methods from the Grid's Editing Inline Live Demo using ToDataSourceResultAsync:

        public async Task<ActionResult> EditingInline_Read([DataSourceRequest] DataSourceRequest request)
        {
            var products = await productService.Read().ToDataSourceResultAsync(request);

            return Json(products);
        }

        [AcceptVerbs(HttpVerbs.Post)]
        public async Task<ActionResult> EditingInline_Create([DataSourceRequest] DataSourceRequest request, ProductViewModel product)
        {
            if (product != null && ModelState.IsValid)
            {
                productService.Create(product);
            }

            var result = await new[] { product }.ToDataSourceResultAsync(request, ModelState);

            return Json(result);
        }

        [AcceptVerbs(HttpVerbs.Post)]
        public async Task<ActionResult> EditingInline_Update([DataSourceRequest] DataSourceRequest request, ProductViewModel product)
        {
            if (product != null && ModelState.IsValid)
            {
                productService.Update(product);
            }

            var result = await new[] { product }.ToDataSourceResultAsync(request, ModelState);

            return Json(result);
        }

        [AcceptVerbs(HttpVerbs.Post)]
        public async Task<ActionResult> EditingInline_Destroy([DataSourceRequest] DataSourceRequest request, ProductViewModel product)
        {
            if (product != null)
            {
                productService.Destroy(product);
            }

            var result = await new[] { product }.ToDataSourceResultAsync(request, ModelState);

            return Json(result);
        }
