MVC 3 specifying validation trigger for Remote validation

I have implemented remote validation using MVC 3 unobtrusive validation as follows The model ``` public class MyViewModel { [Remote("ValidateAction", "Validation")] public string Text { get; set; } } ``` The Controller ``` public partial class ValidationController : Controller { public virtual JsonResult ValidationAction(string aTextToValidate) { if(aTextToValidate == /* some condition */) return Json(true, JsonRequestBehavior.AllowGet); return Json("This is not valid, Try Again !", JsonRequestBehavior.AllowGet); } } ``` The View ``` @using (Html.BeginForm() { @Html.TextBoxFor(m => m.Text) @Html.ValidationMessageFor(m => m.Text) } ``` And that's it, it all works, but ValidationAction is fired on every key press, which is not ideal, I would like just to fire when the element looses focus, but cannot figure how to do this UPDATE Actually I have noted that, by default, the validation does fire onBlur once .i.e. the first time the element looses focus, however when attempting to correct it, validation then fires onKeyUp. I think this is intended functionality and thinking about it is probably quite useful. However it would be useful to know if it is possible to modify this behaviour
