Ajax.NET ProfessionalA quick guide how to start

Because I could not write a documentation I will show you here how to start:

• Download the latest Ajax.NET Professional files from www.schwarz-interactive.de
• Add a reference to the AjaxPro.2.dll (for the .NET 1.1 Framework use AjaxPro.dll)
• Add following lines to your web.config:

<?xml version="1.0" encoding="utf-8" ?><configuration>  <system.web>    <httpHandlers>      <add verb="POST,GET" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro.2"/>    </httpHandlers>  [...]  </system.web></configuration>

• Now, you have to mark your .NET methods with an AjaxMethod attribute:

[AjaxPro.AjaxMethod]public DateTime GetServerTime(){  return DateTime.Now;}

• To use the .NET method on the client-side JavaScript you have to register the methods, this will be done to register a complete class to Ajax.NET:

namespace MyDemo{  public class _Default  {    protected void Page_Load(object sender, EventArgs e)    {      AjaxPro.Utility.RegisterTypeForAjax(typeof(_Default));    }    [AjaxPro.AjaxMethod]    public DateTime GetServerTime()    {      return DateTime.Now;    }  }}

• If you start the web page two JavaScript includes are rendered to the HTML source.
• To call a .NET method form the client-side JavaScript code you can use following syntax:

function getServerTime(){  MyDemo._Default.GetServerTime(getServerTime_callback);  // asynchronous call}// This method will be called after the method has been executed// and the result has been sent to the client.function getServerTime_callback(res){  alert(res.value);}
