Using Required Annotation in the create/update button of a grid


I have a grid in javacsript, with editSettings editMode : "dialogtemplate" and a dialogEditorTemplateID.
I use create and  udpate buttons of the grid to display a Dialog for inserting or updating datas.
I  use a Required dataAnnotation with an error message in my model to handle the obligation of setting a value in some fields but
 it didn't work so those fields aren't require and i don't know how display the error message from my annotation.

I put the Required annotation like this :

[Required(ErrorMessage = "My error")]
public String name {get;set;}

In my view i imported the following script :
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

Thanks for the help,

Hi Cholet,

We understood that you would like to perform Validation using Data Annotation Validators.

Supplier class which holds the data annotation properties of the required columns of Grid and its class name can be given as type of object for the Grid as shown below. This will validate after submitting the form based on the data annotation properties. Refer to the following code example







         . . . ..

      .Columns(col =>


          col.Field("Id").HeaderText("Unique ID").IsPrimaryKey(true).Width(75).Add();

            . . .



namespace CRUDandValidation.Models


    using System.ComponentModel.DataAnnotations;

    public class Supplier


        [Required(ErrorMessage = "ID is must")]

        public int Id { get; set; }

         [RegularExpression(@"^[a-zA-Z0-9 ]{1,10}$")]

        public string PostalCode { get; set; }

         [EmailAddress(ErrorMessage = "Invalid email address")]

        public string EmailAddress { get; set; }


        public string WebAddress { get; set; }

Hi Cholet

JavaScript Grid does not support data annotations. But you can enable validations using ValidationRules property of Grid Colums. Refer to the following code example.

<div id="Grid"></div>

<script type="text/javascript">

    $(function () {


            dataSource: ej.DataManager({

                url: "/Home/DataSource",

                insertURL: "/Home/Insert",

                updateURL: "/Home/Update",

                removeURL: "/Home/Delete"


            allowPaging: true,

             . ..  . . .

            columns: [

                    { field: "Id", isPrimaryKey: true, validationRules: { required: true, messages: { required: "ID is must" }} },

                    { field: "CompanyName", validationRules: { required: true, minlength: 3 } },

                    { field: "PostalCode", validationRules: { range: [0, 1000] } }

                     . . . . .




Refer to the following Help document.


You could also customize the validation rules and frame your own rules. Refer to the following online demo.
