AJAXPage provides a way for server side functions to be called directly from client side code intuitivelly
using the same name and parameters (seamless integration). Check this tutorial.
|
|
|
Using AJAXPage, the user can init a callback to a server side function that will in turn call a WebService and return the value.
No proxy class is needed.
|
|
|
You can call for a panel update on client side by using either a button, a link or anything else.
|
|
|
AJAXPage can do synchronous or asynchronous callback from client to server.
|
|
|
Using AJAXPage, it is very intuitive and easy to run JavaScript code at client after a callback.
|
|
|
AJAXPage allows the user to send only the data that is needed on a panel update.
|
|
|
AJAXPage allows the user to initiate callbacks to own server functions.
|
|
|
Controls in Callback Panel require no extra code to render.
Check these live examples with Literal update and Grid update.
|
|
|
AJAXPage can use collections as parameters on callbacks.
|
|
|
AJAXPage use Unicode characters when doing callbacks.
|
|
|
Sending arguments using AJAXPage control requires the user to make no specific casts.
public void AjaxRequest(int age)
{
// code to handle the AJAX request
// no extra code needed. age is already an integer.
}
|
|
|
Arguments are sent separatelly, no extra code needed.
public void AjaxRequest(string name, int age)
{
// code to handle the AJAX request
// arguments are sent separatelly, no extra code needed
}
|
|
|
AJAXPage allows user to take advantage of "exception driven development", a very useful technique of flow control management.
Users do not need to declare a different handler for each callback made and server side exceptions can be thrown at client
to allow decisions in flow control.
try
{
ob_post.post(...)
}
catch (ex)
{
// an error occured
// handle it depending on type
switch (ex.type)
{
// if database error
case "" : ...
}
}

AJAXPage has an easy way to call client side code from server side.
Can be used anywhere in any server side method called using AJAX.
ExecOnLoad("alert('Hello World!');");
|
|
|
AJAXPage can set values to controls outside of the Callback Panel (SetValue) without any code changes.
