推荐答案
嗨Lakshmi，
看到你的代码后，一切似乎都很完美，除了控制器。因为你错过了在这里发布。
In你的行为是否有像这样的modelstate.isValid
Hi Lakshmi,
After seeing your code everything seems to be perfect, except controller.Since you missed to post it here.
In your action do you have modelstate.isValid like this
public ActionResult actionName(class1 clsObj)
{
if(ModelState.IsValid)
{
// TODO: Add your own logic here
}
else
{
return View(clsObj);
}
}
评论后更新的解决方案，
Updated solution after your comments,
Hey, in ASP.NET MVC3, there's no need to add Html.EnableClientValidation() in view page, instead, just enable the clientValidation in the webconfig file as below:
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
希望这对您有所帮助。
问候，
RK
Hope this helps you a bit.

您好
add课程为
@class =required
Ex： - <％= Html.TextBoxFor（model => model.LastName，new {@class =required}）％>
试试希望这会有所帮助
Hi
add class as
@class = "required"
Ex:- <%= Html.TextBoxFor(model => model.LastName, new { @class = "required" })%>
Try this hope this will help
