Ajax.NET Professional(R)

 

A 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);
}
