Forms validation System.ComponentModel.DataAnnotations and JQuery submit

Question

I have a C# asp.net MVC web application, and I'm using System.ComponentModel.DataAnnotations for form validation.

Here is an example of validation on a password field:

[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; 

In my View, the form has:

@using (Html.BeginForm() {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

I'm planning to use JQuery to Submit my form/model.

Example:

$.post("@Url.Action("Update")",values,function(data)
{
    // do stuff;
});

My question is: will the built-in forms validation still occur, even though I am submitting the data with JQuery?

Yes, it will. The validation in asp.net MVC is done as part of Model Binding. So, when you post your form data to the Update Action, the validation is done when the data is being bound to your Model.
