Check name in AD before submit in create view MVC C#

Question

you can say that I'm new in C# MVC and having some problems, been researching a lot, and this is my first topic here.

I'm developing an application that uses data of active directory. I have a table User that import Data from AD. here is my controller create code:

[HttpPost]
    public ActionResult Create(User user)
    {
        if (ModelState.IsValid)
        {
            DirectorySearcher directorySearch = new DirectorySearcher();
            directorySearch.Filter = "(&(objectClass=user)(SAMAccountName=" + user.IdUser + "))";
            SearchResult results = directorySearch.FindOne(); 
             if (results != null)
            {
                if (results.Properties.Contains("mail")) //E-mail
                  {
                      user.E_mail = results.Properties["mail"][0].ToString();
                  }
               else
                  {
                     user.E_mail = string.Empty;
                  }
                if (results.Properties.Contains("c")) //Country
                {
                    user.Country = results.Properties["c"][0].ToString();
                }
                else
                {
                    user.Country = string.Empty;
                }


            }

            db.User.Add(user);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.CompanyCode = new SelectList(db.Company, "CompanyCode", "CompanyName", user.CompanyCode);
        ViewBag.Country = new SelectList(db.Country, "CountryName", "CountryName", user.Country);
        return View(user);
    }`

this is some of my create view code:

    <div class="editor-label">
        @Html.LabelFor(model => model.IdUser)

    </div>

    <div class="editor-field">
        @Html.EditorFor(model => model.IdUser)
        @Html.ValidationMessageFor(model => model.IdUser)

what I want to do is check in the AD if the user really exists with a function and return the value to the IdUser field but before click the submit, just like a check names.

A solution that I was thinking of, in the view just put a button:

        <p>
    <input type="submit" value="Check" onClick="CheckFunction(model.IdUser)" />
    </p>

and the function is something like:

        public string CheckFunction(string Id)
    {
            DirectorySearcher directorySearch = new DirectorySearcher();
            directorySearch.Filter = "(&(objectClass=user)(SAMAccountName=" + Id + "))";
            SearchResult results = directorySearch.FindOne();
            if (results != null)
            {
                return Id;
            }
            return string.Empty;
    }

but the problem is that I dont know how to set the Id string returned in Function to the model.IdUser field.

Can you guys help me?

do an ajax jquery call to the controller. see my answer here http://stackoverflow.com/questions/19359204/asp-net-mvc-4-passing-object-variable-through-actionlink/19360998#19360998. in the success you can set the result to the id field using $('.IdUser').val(result.id) or whatever you pass back — Matt Bodily, Nov 06 '13 at 20:40
Don't know if I understand, could you explain more detailed? — user2962069, Nov 06 '13 at 21:49

you will need to put a class on your button (class="btnSave" for the code below)

$('.btnSave').on('click', function(e){
    $.ajax({
        url: '@(Url.Action("CheckFunction", "Controller"))',
        type: 'post',
        data: {
            //this is the id that is passed.  change @Model.Id to whatever id you want sent
            Id: '@Model.Id'
        },
        success: function (result) {
            if(result.Success){
                //if this is a submit button it will do a post back.  If just a button you can set fields with the returned data or alert, etc
                $('.fieldId').val(result.Id);
            }else{
                //e.preventDefault() will stop the submit button from submitting if failed is returned
                e.preventDefault();
                //do something for failure (alert or something)
            }
        }
    });
});

then change your controller to return json for success or failure. here is an example for that json success and fail response in MVC
