In this post I’ll explain how to populate a select dropdownlist using jQuery and Ajax. I am using an ASP.NET web application and page methods to perform the Ajax calls. Using page methods means that you do not need a seperate web service, which is good if the functionality is specifically for the page. The page methods must be declared public static and use the WebMethod attribute.
It is fairly common to have a list of records with a hyperlink to delete a record. The problem here is that with MVC the hyperlink will use a GET request to delete a record. This is a fairly big security issue as anybody can browse to the URL and delete a record from your system. In this post I’ll explain how you can use the Ajax helpers to create a hyperlink that will call your delete method without using GET.

In this post I talked about how to use the jTemplates plugin for jQuery. Using my final example in the post I thought it would be cool to try and add some ‘edit in place’ functionality to the table.
For this to work I’ve created a Data Access Layer using Linq to XML. My web service then uses this DAL to save and retrieve my data.

A guy in work introduced me to jTemplates, a template engine plugin for jQuery. It allows you to easily bind JavaScript objects to a defined template and also has some other nifty features.
I’ve found jTemplates to be particularly good when using ajax to display any information quickly and easily.
First I’ll explain how to create a simple template to display data, and then how to use the foreach and cycle features.
