[Required(ErrorMessage = "Error")]
[RegularExpression(#"^[0-9\.]*$",ErrorMessage="Error")]
public string Scode { get; set; }
My View:
#Html.ValidationSummary(true)
#using(Html.BeginForm("CreateSharshomari", "VahedInfo", FormMethod.Post))
{
#Html.TextBox("Scode")
#Html.ValidationMessage("Scode")
<input id="BtnErsal" type="submit" value="ارسال" />
}

Have you imported required jQuery files as below? If not , then I would invite you to do so.
<script src="#Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
Given your model:
public class MyViewModel
{
[Key]
public int Id { get; set; }
[Required(ErrorMessage = "Error")]
[RegularExpression(#"^[0-9\.]*$",ErrorMessage="Error")]
public string Scode { get; set; }
}
Controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new MyViewModel());
}
[HttpPost]
public ActionResult Index(MyViewModel model)
{
return View(model);
}
}
View:
#model SomeAppName.Models.MyViewModel
<script src="#Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
#using(Html.BeginForm("CreateSharshomari", "VahedInfo", FormMethod.Post))
{
#Html.ValidationSummary(true)
#Html.TextBox("Scode")
#Html.ValidationMessage("Scode")
<input id="BtnErsal" type="submit" value="ارسال" />
}
Note that you must have following keys in the Web.config file, for validtion to work on client side:
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
Or in the App_Start
protected void Application_Start()
{
//Enable or Disable Client Side Validation at Application Level
HtmlHelper.ClientValidationEnabled = true;
HtmlHelper.UnobtrusiveJavaScriptEnabled = true;
}
