I came across a situation where I needed to make sure at least one checkbox in an ASP.NET CheckBoxList is checked before submitting the page. Looking at the source each checkbox element created shares the same client ID with a different number at the end, so I needed a way to select all checkboxes where the ID started the same.
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.
In this post I’ll show how to use jQuery to automatically convert all email addesses from static text into a mailto link.
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.
Earlier today I needed to force a clide side event to fire programatically using jQuery.
I found you can do this easily with the jQuery trigger method:
$("#myControl").trigger("change");
The above will trigger the change event of the control with ID ‘myControl’

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.

Making ajax calls to an ASP.NET web service using jQuery is too easy. In this post I’ll explain how to do it!
The Each method in jQuery is pretty useful and can be used to iterate through the elements within a jQuery object.
I’ve been using it recently to iterate through JavaScript arrays. It saves having to use a for loop and the code looks nicer.
