[CLOSED] Get value from textfield in controller [Razor]

[boris]

When using direct click on button i can get value form one textfield in controller, but when use direct click in button on window value of textbox is null.

This is a textfield:

@Html.X().TextField().ID("tfID").FieldLabel("Labela 23").Text("Some text ...")

This example works:

@(Html.X().Button()
        .ID("btnID2")
        .Text("Direct event 2")
        .DirectEvents(directEvents => 
        {
            directEvents.Click.Url = "/Account/TestMethod";
        })
    )

and controller:

public ActionResult TestMethod(string tfID) 
        {
            AjaxResult r = new AjaxResult();
            r.Script = X.Msg.Alert("", "Vrednost: " + tfID).ToScript();
            return r;
        }

But in this example where I only use Window it is not work:

@(Html.X().Window().ID("WindowLogIn")
        .Layout(LayoutType.Anchor)
        .Width(300)
        .Height(150)
        .Title("Test")
            .Items(item =>
            {
                item.Add(Html.X().Button().ID("ButtonPrijava").Text("Prijavi me").DirectEvents(directEvents => { directEvents.Click.Url = "/Account/TestMethod"; })); 
            })

    )

For both examples I put razor code in BeginForm

@using (Html.BeginForm())
{
}

Can you help me to handle this data from textbox in controller.
