    Hi,

    - AutoPostBack requires '<form runat="server"'
    - Do not define OnDirectClick and AutoPostBack for one button because direct click handler will not be executed correclty due page hard reloading (postback)
    - To handle postback use OnClick handler
    - If you use ASP.NET MVC then do not use server side handlers inside views, use controller actions for that

    There is some issue with server post back handler? Am I missing something?

    [QUOTE=Vladimir;98724]Hi,

    - AutoPostBack requires '<form runat="server"'

    - Do not define OnDirectClick and AutoPostBack for one button because direct click handler will not be executed correclty due page hard reloading (postback)- I had put AutoPostBack for trying. keeping only OnDirectClick don't work.

    - To handle postback use OnClick handler - Using OnClick also don't seem to work

    - If you use ASP.NET MVC then do not use server side handlers inside views, use controller actions for that - On this button click, I need value from a text box which is not binded to model. This text box is only for taking input. How I am suppose to take this text box value directly in controller method?

    Hi @alscg,

    Please use [QUOTE] tags to wrap quotes.

    Regarding the problem.

    Please refer a controller action via URL and pass a required data via ExtraParams.

    Example View
    <!DOCTYPE html>

<html>
<head>
    <title>Ext.Net.MVC v2 Example</title>    
</head>
<body>
    @Html.X().ResourceManager()

    @(Html.X().Button()
        .Text("DirectEvent")
        .DirectEvents(de =>
        {
            de.Click.Url = Url.Action("TestDirectEvent");
            de.Click.ExtraParams.Add(new { test = "Hello!"});
        })
    )
</body>
</html>
    Example Action
    public ActionResult TestDirectEvent(string test)
{
    X.Msg.Alert("Server", test).Show();

    return this.Direct();
}
    Also you can use a DirectMethod, see #3:

    Form Button Direct Event return view

    "
    Example Action
    public ActionResult TestDirectEvent(string test)
{
    X.Msg.Alert("Server", test).Show();

    return this.Direct();
}
    "


    Hi Danil,


    In the above action you mentioned this.Direct() but i am unable to get this method or view. Its showing an error that no extension method is written.

    I am using Ext.net 2.0 and MVC4.

    Could you please provide a solution to resolve this.

    Thanks & Regards,
    Chinni

    Hi @chinninani,

    Please clarify what Ext.NET version are you using?

    Is there the following in the controller?
    using Ext.Net.MVC;
