Hello

Excellent article, but I have a big problem: how to make the validation within the modal dialog?. I need to show the model System.ComponenModel.DataAnnotations and other custom messages, can you help me?

Rohit said...

yes. You can add validation such as Required, Length of String, Regular Expression, by using System.ComponenModel.DataAnnotations and check in your post method whether ModelState.IsValid or not or any other custom validation, if valid then only perform your operation.

How do I change the App so that it provides for Validation??
I guess you'll have to do something so...

public ActionResult Create(HttpPostedFileBase imageFile, Actor model, string cmd)
{
if (ModelState.IsValid)
{
..... What should I put here so that it shows the partial view with the validation errors???
}
}

Thanks

Server side modification:

bool success = false;
string message = "Model State is not valid!";

if (ModelState.IsValid)
{
success = true;
message = "Model State is valid!";

// to do
}

return Json(new { success = success, message = message }, "application/json", JsonRequestBehavior.AllowGet);


Client side modification:

$('#frmCreateActor').ajaxForm(function (response) {

if (!response.success) {
alert(response.message);
return;
}

$('#modalDialog').dialog("close");
})

Hope this help.

In that view I put...

$('#frmCreateActor').ajaxForm(function (response) {

if (!response.success) {
alert(response.message);
return;
}

$('#modalDialog').dialog("close");
})

In _Actor.cshtml and _ActorList.cshtml i have error in runtime JavaScript: the object don´t accept the property or method 'ajaxForm' ....

Help Me!!!

Please check whether you have added this mentioned file or not:
script src="@Url.Content("~/Scripts/form_ajax.js")"

and
in _Actor.cshtml, the complete script code is given below:
script
$(document).ready(function () {
$('#frmCreateActor').ajaxForm(function (response) {

if (!response.success) {
alert(response.message);
return;
}

$('#modalDialog').dialog("close");

$.post('@Url.Action("GetActorList", "Home")', function (data) {
$("#actorList").html(data);
});
})
});
script

The complete script tag is not allowed in comment box thats why I had not created script tag properly. Please correct it in your code.
