Asp.Net MVC3 With required field validation

Question

I have created one view ,in which i have one text box,i want to put required field validation on that text box.

@Html.TextBox("txtFirst", "", htmlAttributes: new {@maxlength="9"})

Are you asking for the validation in the Domain object to be incorporated? — MikeTWebb

This is not how it's being done. you should learn how to use the jQuery validation plugin — gdoron

First I must say the best way to do validation in MVC is to put the Data Annotation attributes above the properties in your model like with this:

[Required]
[StringLength(9)]
public string Foo {get; set;}

// This will force the validation in the client side.
@Html.TextBoxFor(m => m.Foo);

The good thing in this approach(except that it's usually less to write) that it work client-side and Server-side as well.

If you want to do the validation in the view and not in the Model for some reason, you simply need to add the required class to the textbox:

@Html.TextBox("txtFirst", "", htmlAttributes: new {@class = "required", maxlength="9"})

All this gets is client side validation - client side can still be bypassed and if server side validation isn't in place then there is a data integrity problem

Hy,Above thing solved my issue,but now i want 2 validation for same field.For e.g:@Html.TextBox("txtFirst", "", htmlAttributes: new { @class = "required email", maxlength = "9" }) this field is required and it must be valid email this solved my problem but i am not able to display different validation message,it means if user not enter value then error message is please enter email address and wrong email address then it should display please enter valid email.please keep in mind i don't want to use model for that,i want to use view only.
