Hi Ishan, 

Greetings from Syncfusion support. 

We have prepared sample based on your requirement using Required and MaxLength validation. Please find the sample below. 

@using (Html.BeginForm()) 

{ 

    @Html.ValidationSummary(true) 

    <div class="col-lg-12 control-section"> 

        <div id="wrapper"> 

            @Html.EJS().NumericTextBoxFor(model => model.value).Width("200px").Render() 

            <div> 

                @Html.ValidationMessageFor(model => model.value) 

            </div> 

            <div id="submitbutton"> 

                @Html.EJS().Button("btn").Content("Post").Render() 

            </div> 

        </div> 

    </div> 

} 

[Controller] 

public class NumericValue 

    { 

        [Required] 

        [Range(1, 10)] 

        public int value { get; set; } 

    } 

 

    public class HomeController : Controller 

    { 

        public ActionResult Index() 

        { 

            NumericValue val = new NumericValue(); 

            val.value = 10; 

            return View(val); 

        } 

        [HttpPost] 

        public ActionResult Index(NumericValue model) 

        { 

            NumericValue val = new NumericValue(); 

            val.value = model.value; 

            return View(val); 

        }
