Save HTML tag in Grid/Inline editing content

[Hyewon]

I'm making the Grid/Inline editing list using Kendo UI MVC referring this: https://demos.telerik.com/aspnet-mvc/grid/editing-inline 

I was trying to create and update text with HTML tag, for example, <br>, <h> with some other texts.

But whenever I put HTML tags such as those and even like '<b', '<h', it wasn't created or updated.

They're not updated and created like this image below:

Hello Hyewon,

This behavior is a validation feature enabled in ASP.NET MVC by default. HTML input for certain Actions or ViewModel properties could be allowed by:

• Setting [AllowHtml] attribute on a ViewModel property allows HTML input for this property only. This is the recommended way to enable HTML input:

        [Required]
        [DisplayName("Product name")]
        [AllowHtml]
        [Remote("IsProductName_Available", "Validation")]
        public string ProductName
        {
            get;
            set;
        }

• Setting [ValidateInput(false)] attribute on an Action will disable the validation on the whole Action:

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

            return Json(new[]{product}.ToDataSourceResult(request,ModelState));
        }
