Elegant ASP.NET Library for Ajax

Category: .NET

<>p> Fexis Vargas pointed us to Jason Diamond, a DevelopMentor instructor, who has created his own Ajax library for making callbacks to the code behind an ASP page. It started out as an “intellectual exercise”, but he did such a good job, its turning into an open source project, whether he likes it or not :-).

Using his library, developers can write callback methods into the class like this:

public class WebForm1 : Page {
    void Page_Load() {
    [Ajax.Method] double Add(double a, double b) {
        return a + b;

and then from the ASP template reference the callback in this manner:

<input id="a" /> + <input id="b" /> = <input id="c" /><br />
<input type="button" value="Add"
    onclick="document.getElementById('c').value = 
    document.getElementById('b').value);" />

Pretty slick.
