A Quick Guide How to start : AjaxPro

원문 : http://www.ajaxpro.info/quickguide.aspx

1. Download the latest Ajax.NET Professional files from www.schwarz-interactive.de
2. Add a reference to the AjaxPro.2.dll (for the .NET 1.1 Framework use AjaxPro.dll)
3. 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>

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

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

5. 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;
    }
  }
}

6. 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);
}
