Building a jQuery-Powered Tag-Cloud

Tag-clouds are easy to do badly; whether from a design perspective or from a code perspective. Thanks to jQuery, it’s also easy to do well. We’ll be using the hot new 1.3 version of jQuery for this example and will be working with PHP and MySql to provide a JSON feed of our tags. Getting the tags into a database in the first place is beyond the scope of this tutorial, but it’s a simple enough matter to retrieve and pass them to a waiting page via AJAX.

ELO - javascript / PHP cliente/server (Ajax Push)

Server and client integration (Ajax push or comet on PHP) A JavaScript/PHP library implements ajax push to be used in ONE javascript line code. Uma biblioteca JavaScript/PHP implementa ajax push a ser uasdo em UMA linha de código JavaScript ****************************** Tche, eu desenvolvi esta biblioteca JavaScript/PHP para oferecer de uma forma muito mais dinâmica o AjaxPush ao desenvolvimento. Em uma única linha de comando, pode-se estabelecer uma ligação entre o conteúdo em server side e o client side, sem que sejam necessarias diversas chamadas em Ajax, simplesmente. Aí está um exemplo do funcionamento desta biblioteca, onde o arquivo "escutado" escreve o conteúdo de determinado diretório no servidor. Foi especificado nesta unical linha javascript que ... assim que o arquivo php escrever algo diferente,este conteúdo será escrito em uma DIV.Como o arquivo php lista os arquivos do diretorio,assim que eles são alterados,o cliente é avisado,e "a mágica acontece".É interessante que a,implementação [...]

WaveMaker Visual Ajax Builder (tutorial #1)

Wave Maker 4.0 is a nice visual ajax devlopment enviornment comparable to visual studio for its drag-and-drop easy interface, and javascript framework (which includes dojo, spring, and a few others). It also allows for web services and database interactions, all without needing much code. It is very easy and quick to use for building "web 2.0", or rather "new century", web applications.

jQuery & Ajax Fun: Implementing a Paging Listbox

Many times in web forms we need to provide a listbox with lots of elements, A good solution is to filter and page these elements to speedup page loading and optimize DB/Network usage..

This is a complete implementation of a paging listbox using jQuery on client side and ASP.Net on server side. and should look like this..

The form web page, which also contains the JavaScript class to build the select box, of course don't forget to download the jQuery library.
<html>
<head>
<title>jQuery & Ajax Fun: Implementing a Paging Listbox</title>
<script type="text/javascript" src="JS/jquery-1.3.min.js"></script>
<script type="text/javascript">
function AjaxListBox() {
   this.source = '';
   this.divID= '';
   this.keyID= '';
   this.buttevent_event_on__ID='';
   this.lastKey= '';
   this.startup= true;
   this.minWidth=0;
   this.position [...]

PagerTemplate per GridView

Molto spesso mi capita di vedere griglie che mostrano l’intero set di dati senza fornire un accesso tramite paginazione. Personalmente credo che offrire solo un sottinsieme di record sia fondamentale.
Premetto che l'’intento di questo post non è quello di parlarvi della paginazione, dei benefici che questa può portare all’applicazione, nè tantomeno realizzare un custom paging.
A tal riguardo trovate moltissimo materiale in rete, giusto per citare qualche fonte:
ASP.NET Custom Paging with GridView using ObjectDataSource
GridView Paging using ASP.NET AJAX Slider Extender

Quello che invece cercherò di illustrare è come sia possibile personalizzare il paging del controllo GridView utilizzando il property PagerTemplate.
Ma partiamo con ordine, descrivendo a grandi linee l’idea: unire un paging a una scrollbar. Tramite i due classici pulsanti next e prev sarà possibile [...]
