Use ASP.NET MVC validation with jquery ajax?

Question

I have simple ASP.NET MVC action like this :

public ActionResult Edit(EditPostViewModel data)
{

}

The EditPostViewModel have validation attributes like this :

[Display(Name = "...", Description = "...")]
[StringLength(100, MinimumLength = 3, ErrorMessage = "...")]
[Required()]
public string Title { get; set; }

In the view I am using the following helpers :

 @Html.LabelFor(Model => Model.EditPostViewModel.Title, true)

 @Html.TextBoxFor(Model => Model.EditPostViewModel.Title, 
                        new { @class = "tb1", @Style = "width:400px;" })

If I do a submit on a form that this textbox is placed in a validation will be done first on client and then on service(ModelState.IsValid).

Now I got a couple of questions :

1. Can this be used with jQuery ajax submit instead? What I am doing is simply remove the form and on clicking the submit button a javascript will gather data and then run the $.ajax.

2. Will the server side ModelState.IsValid work?

3. How can I forward validation problem back to the client and present it as if Im using the build int validation(@Html.ValidationSummary(true))?

Example of Ajax call :

function SendPost(actionPath) {
    $.ajax({
        url: actionPath,
        type: 'POST',
        dataType: 'json',
        data:
        {
            Text: $('#EditPostViewModel_Text').val(),
            Title: $('#EditPostViewModel_Title').val() 
        },
        success: function (data) {
            alert('success');
        },
        error: function () {
            alert('error');
        }
    });
}

Edit 1:

Included on page :

<script src="/Scripts/jquery-1.7.1.min.js"></script>
<script src="/Scripts/jquery.validate.min.js"></script>
<script src="/Scripts/jquery.validate.unobtrusive.min.js"></script>

Client Side

Using the jQuery.validate library should be pretty simple to set up.

Specify the following settings in your Web.config file:

<appSettings>
    <add key="ClientValidationEnabled" value="true"/> 
    <add key="UnobtrusiveJavaScriptEnabled" value="true"/> 
</appSettings>

When you build up your view, you would define things like this:

@Html.LabelFor(Model => Model.EditPostViewModel.Title, true)
@Html.TextBoxFor(Model => Model.EditPostViewModel.Title, 
                                new { @class = "tb1", @Style = "width:400px;" })
@Html.ValidationMessageFor(Model => Model.EditPostViewModel.Title)

NOTE: These need to be defined within a form element
