Ext.Direct for ASP.NET MVC

[sspark]

How about same name of Contrller in Different Area ?

I tried to access http://<host>/Direct/Api, then I got error which is "Action Options has already been configured".
Because, I have same name of Controllers in different Areas.

37534 if(!provider.events){
37535 provider = new Ext.Direct.PROVIDERS[provider.type](provider);
37536 }

it is weird, demo work ok using local server http://localhost:53794/Default.aspx in the same computer I change the application to run on IIS and I get http://app.demo.com/Direct/Api 404 Not Found, someone is testing the version 2.0 with IIS6 ? I was testing old version Ext.Direct.Mvc-0.6.2 and work ok with IIS6

Great job! Many thanks for that. Just the push in the back I needed, since i'm new to mvc .net and extjs. Will study on it!

[halcwb]

I keep running in a System.NullReferenceException: DirectRequest is null exception. I post a form to the following controller:

[FormHandler]
        [ValidateInput(false)]
        public ActionResult GenFormLogin(string user, string password)
        {
            bool login = (Informedica.GenForm.Library.Security.
                           GenFormPrincipal.Login(user, password));

            //return this.Direct(new LoginResponse(login, "failure"));
            return this.Direct(RoleNameList.GetNameValueList());
        }

        [Serializable]
        private class LoginResponse
        {
            private bool _Success;
            private string _Title;

            public LoginResponse(bool success, string title)
            {
                _Success = success;
                _Title = title;
            }

            public bool Success
            {
                get { return _Success; }
                set { ;}
            }

            public string Title
            {
                get { return _Title; }
                set { ;}
            }
        }

When I debug my code, the program passes the controller code without problems. But in my webbrowser I get the null reference exception. The javascript code I use to submit the form is:

                handler : function() {
                    loginForm.getForm().submit({
                                success : function(f, a) {
                                    debugger;
                                    Ext.Msg.alert('Success', 'It worked');
                                },
                                failure : function(f, a) {
                                    debugger;
                                    Ext.Msg.alert('Warning', a.failureType);
                                }
                            });
                }

But I do not think the problem is not on the client side but in my this.Direct return object. I also tried passing a null, boolean, string, anonymous class like : new { succes = true, title: "failure} etc...

Any help will be greatly appreciated.

In the project I just completed, we dynamically load views on each tab so that all of the code doesn't have to be loaded at once. It also allows you to dynamically populate the code with some data, which can help maintain security.

//in the code that initializes ExtJS you set:
Ext.UpdateManager.defaults.loadScripts = true;

//item that auto executes a view (the only property that is required is the autoLoad,
//but I show some other properties to give some context.

var Items = 
[
   {
        region: 'center',
        layout: 'anchor',
        id: 'YourId',
        autoLoad: 'yourViewFolder/yourView'
    }
];

We could also use a function to load a view script (or external js file on the fly)

YourApp.RunScript = function(url, fn)
{
	if (Ext.isDefined(fn))
	{
		fn();
	}
	else
	{
                      if (! Ext.isDefined(YourApp.ScriptContainer))
                      {
                           YourApp.ScriptContainer = new Ext.Window
                           ({ x:-100, y: -100, hidden: true, autoDestroy: false, hideMode: 'offsets' });
                      }
		YourApp.ScriptContainer.add(new Ext.Panel({ autoLoad: url, hidden:true } ));
		YourApp.ScriptContainer.doLayout();
	}
};
YourApp.RunScript('/yourFolder/yourView', yourFunctionInFile)

With this arrangement we had only one view page running at the time, but it could load child views of code in new tabs. This way we didn't have to load all of the code at once, but we could dynamically load new code any time we wanted to. The loaded code could use any common objects we wanted. The other nice thing about this code is that it could be called more than once. If the code was already loaded, it runs fn(), but if not it autoloads the code and runs the code.

I'm building an app that doesn't need much in the way of controls, but the directRequest handlers and data stores would be nice.

What is the minimum Javascript code that needs to be included to handle DirectRequests and have data store objects. Or is this too complicated to even be considered as an option?

Update: So far, trying to load the least amount of code hasn't worked. Going thru the API help documents, I've loaded about a dozen js files and I still have issues. This is approaching perhaps one third of the entire ext-all, so perhaps this isn't worth doing.
