hi folks, if you want to validation phone number annotation in MVC.

use this code which is shown below:

        <li class="cell last" style="width: 60%;">Phone Number:</li> 
        <li class="cell last" style="width: 60%;">

            @Html.TextBoxFor(model => model.PhoneNumber, new { @class = "textbox" }) @Html.ValidationMessageFor(model => model.PhoneNumber)

        </li>

please check your Models and Views properly:

@Html.LabelFor(model => model.PhoneNumber)

@Html.EditorFor(model => model.PhoneNumber)

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

this Data Annotation alone is enough if you need regex for validation. as you want to using data annotation so its helpful for you which is shown below:

Syntax:

[RegularExpression(@"^([0]|\+91[\-\s]?)?[789]\d{9}$", ErrorMessage = "Your entered Mobile No is not valid.")]

Code:

public class PersonModel

{

    [Display(Name = "Mobile Number:")]

    [Required(ErrorMessage = "Mobile Number is required.")]

    [RegularExpression(@"^([0-9]{10})$", ErrorMessage = "Your entered no is Invalid.")]

    public string MobileNumber { get; set; }

}

I hope, It will be helpful for you.

Happy Coding :)
