after that ,you should change your call action in javascript like this:
synchronous
var response = MyClass.myMethod(null,myArgs);
if (response >= 2) {
--- code here ---
}

asynchronous
MyClass.myMethod(function(response) {
if (response >= 2) {
--- code here ---
}
},myArgs);

Actually,just make javascript support overload ,then DynAjax can support overload too.By the way,I have made DynAjax support jQuery.
-----------------------------------------------
dynAjax.aspx (for jQuery)
-----------------------------------------------
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Ajax.aspx.cs" Inherits="WWW.Scripts.Ajax" %>
function DynAjaxManager(){}
DynAjaxManager.prototype = {
initialize: function() {},
getDynaData: function(callBackMethod,classId,methodName,args) {
var dynaResult = null;
var asyncCall = false;
if (callBackMethod && typeof callBackMethod == "function") {
asyncCall = true;
}
$.ajax({
type:"POST",
url:"_AjaxHandler.aspx",
data:"classId=" + encodeURIComponent(classId) + "&methodName=" + encodeURIComponent(methodName) + "&methodArgs=" + encodeURIComponent(JSON.stringify(args)),
async:asyncCall,
success:function(request){
dynaResult = eval('('request')');//JSON.parse(request);
if (callBackMethod) {
callBackMethod(dynaResult);
}
},
error:function(e) {
dynaResult = null;
if (callBackMethod) {
callBackMethod(dynaResult);
}
}
});
return dynaResult;
}
};
var dynAjaxManager = new DynAjaxManager();

//this method can make javascript support overload
function DynAjaxAddMethod(object, name, fn){
var old = object name ;
object name = function(){
if ( fn.length == arguments.length ){
return fn.apply( this, arguments );
}
else if ( typeof old == 'function' ){
return old.apply( this, arguments );
}
}
};

<%= dynamicJsText %>

-----------------------------------------------
dynAjax.aspx.cs
-----------------------------------------------
... ....
/// <summary>
/// create【class】
/// </summary>
/// <param name="classNode"></param>
protected void addClassDefinition(XmlNode classNode)
{
string className = classNode.Attributes"id".Value;
dynamicJsText += "function " + className + "DYNClass(){";

XmlNodeList nodesList = classNode.SelectNodes("dynajax:method", nsmgr);
for (int i = 0; i < nodesList.Count; i++)
{
addMethodDefinitionReload(className, nodesListi);
}
dynamicJsText += "\n};\n";
dynamicJsText += "var " + className + " = new " + className + "DYNClass();\n\n";
}
/// <summary>
/// create【overload javascript methoed】
/// </summary>
/// <param name="className"></param>
/// <param name="methodNode"></param>
protected void addMethodDefinitionReload(string className, XmlNode methodNode)
{
XmlNodeList paramsList = methodNode.SelectNodes("dynajax:param", nsmgr);
string paramsListStr = "";
string separator = "";
foreach (XmlNode paramNode in paramsList)
{
paramsListStr += separator + paramNode.Attributes"name".Value;
separator = ",";
}

string methodName = methodNode.Attributes"name".Value;
if(paramsList.Count!=0){
dynamicJsText += "\n DynAjaxAddMethod(this,\"" + methodName + "\",function(callBackMethod," + paramsListStr + ") {\n";
}else{
dynamicJsText += "\n DynAjaxAddMethod(this,\"" + methodName + "\",function(callBackMethod) {\n";
}
dynamicJsText += " var args = " + paramsListStr + ";\n";
dynamicJsText += " return dynAjaxManager.getDynaData(callBackMethod,'" + className + "','" + methodName + "',args);\n";
dynamicJsText += " });";
}

Hello Kaima,

thank you for your post.
no, DynAjax doesn't support overload, and I'm interested in your idea to make it support overload...
It's a pleasure to see people who are interested in DynAjax improvements, don't hesitate to give us more and more feedbacks.

This would be a cool feature.Thanks for your efforts.

Now ,I doubt that DynAjax can support "overload method" or not?

if can't,I have a idea to make DynAjax support "overload ".

Hello all,

as you can see, latest release (v1.05) implements a great new feature: Server exceptions trapping.
Every exceptions trhown on server side can be catched and interpreted in different ways on client side.

Thanks for your support and downloads,

DynAjax

Project Description

DynAjax is a Javascript / Ajax / ASP.Net / C# Framework easing dynamic calls to business / service C# methods directly from JavaScript code (like DWR framework does in Java World). The object serialization is based on JSON, permitting complex objects exchange.

Download latest release (v1.05)

DynAjax v1.05

What is DynAjax ?

DynAjax is a development framework based on C# .Net / ASP .Net on server side and Prototype on client side (Javascript useful library) that permits direct call of server side C# methods from client side Javascript.

Who is DynAjax for ?

Every C# / ASP .Net developpers who want to add efficient and easy to use Ajax to their web applications and professional developments (I created it for my own professional needs / use).

What can DynAjax do ?

Imagine you're developping a professional web application and you need to save a text typed by user into the database without posting HTML Form and reloading the entire page. Obviously, you'll use the Ajax technology for that.
What about defining entire XmlHttpRequest (Ajax) request and check the response codes etc. to send data and be sure it has been saved correctly ? it's boring.
With DynAjax, you can save this text via the following JavaScript code (suppose you get a public method called 'saveText' into your class 'MyClass' that returns the string "ok" if everything was fine) :

var response = MyClass.saveText(myText);
if (response == "ok") {
    --- code here ---
}

Very simple to use, isn't it ?
Visit Samples page to get a lot of sources / samples.

Is DynAjax synchronous or asynchronous ?

It's up to you: if you want DynAjax to be synchronous, use the following code:

var response = MyClass.myMethod(myArgs);
if (response >= 2) {
    --- code here ---
}

Now you want an asynchronous call, just use the second syntax:

MyClass.myMethod(myArgs, function(response) {
        if (response >= 2) {
            --- code here ---
        }
    });

DynAjax recognizes automatically the way you want it to be used.

What kind of data can be returned by DynAjax to client JavaScript ?

Data of almost any type can be returned by server. Actually, data are transmitted in JSON format (an exchange format between JavaScript and other languages, including C# .Net).
This format permits the following data types:

Strings
Numbers (int, decimal...)
Booleans
Arrays
HashTables
Complex objects (made of Properties, Arrays, HashTables, Arrays of other complex objects etc.)
"null" value

As you can see, almost everything is possible: you can, for example, if you need to develop a site like eBay, call a method that return a list of Product instances to display on user search - you just have to iterate on list and have access to all Product instances properties as you were in C# code.
Please visit Json description site if you want further informations about this format.

What about security ?

DynAjax provides security checks on all methods you can call remotely.
Actually, each method has to be defined into an XML configuration file and you can specify wether it needs - or not - authentication on your application.
Thus, hackers aren't able to call remote methods without granted access.

Is it difficult to install / set up DynAjax into my web application ?

No, DynAjax is based on 8 files :

DynAjaxHandler.aspx and DynAjaxHandler.cs - the Ajax handler that will receive and dispatch all DynAjax calls
dynAjaxScript.aspx and dynAjaxScript.cs - the dynamix JavaScript part of DynAjax (it's JavaScript, though its extension is .aspx)
prototype.js - the prototype framework
Newtonsoft.Json.dll - a Json library for .Net
log4net.dll - logging library
dynAjaxConfig.xml - the DynAjax configuration file (in XML format)

These 8 files must be copied into your web application directory, and only the dynAjaxConfig.xml needs to be updated to suit your needs.
Pretty easy, no ?
Take a look at the first tutorial DynAjax tutorial 01 to get step by step DynAjax configuration.

How do I configure my methods definition ?

You can visit this Wiki page: configuration, everything's explained.

Who supports this framework ?

Me (Mr Benoît BEGUIN) and my company Odesys. Feel free to contact us at admin@dynajax.org to get informations, report bugs or suggest new features.

Exception management added - now DynAjax can handle server exception and propose custom events New XML schema

NEW POST: This Framework is COOL!

magicben — Wed, 02 Apr 2008 20:49:50 GMT

Thank you very much,
and this is only the beginning, brand new cool features will be added soon:
- reverse ajax (server will be able to call javascript methods)
- exception management (server exceptions will be treated as you want: send null, call methods... cool stuff)
- class proxy: DynAjax will permit to expose not only methods but CLASSES as well.

Thank you again,
