I'm in the process of rewriting mikesdotnetting.com using the ASP.NET MVC framework. It's an interesting experience, in that this is my first exposure to MVC. The first stumbling block I encountered was how to pass data in a satisfactory way to Partial Views which only represent part of the data that is to be displayed in the View. Since I struggled to find clear guidance on this, I thought I would share a way to do it.

I've recently done a series of articles that feature calling databases via AJAX using jQuery. In pretty much all of the articles, I have used Web Services as my data access mechanism. Judging from the comments that some of the articles have attracted, this has caused a little confusion. But Web Services is just one mechanism. Page Methods and simple ASPX files are two more. And finally, as pointed out by a commenter, Benny Halperin, ASHX files are yet another option. In this article, I shall review each of these approaches.

IP addresses can reveal a lot about your web visitors. For an ecommerce site, the owner or registrant of the visitor's IP address can be very useful information. You could paste each visitor IP address into one of the many free IP Lookup sites available, but that can be time-consuming and tedious. Or you could build your own lookup. This article shows how this can be done pretty quickly.

This article looks at efficient use of jQuery tabs when displaying data. Specifically, it covers how to lazy-load data, so that it is only accessed and displayed if the tab is clicked.

It was bound to happen - you knock up an article on jQuery draggables one day, and the next, someone like Jim ;-) comes along and asks about persisting the position of the dragged item across Postbacks, or even sessions. I suppose it's my fault - I mentioned using draggables in a previous life in the context of saving the position, so it's only fair I share how that's done.

One of the keystones of modern AJAX-enabled web sites is Drag and Drop. This article looks at the current state of Draggables that form part of the jQuery UI Library.

It's a common problem: you have a registration form, but you want to prevent user names or other values from being used more than once. You need a user-friendly way to prevent duplicate values being submitted. This is where the simplicity of jQuery excels.

My simple article on Ajax with Classic ASP is one of the most popular on this site. So I thought it's about time I updated it to show how to use jQuery to Ajaxify a Classic ASP page. Since I did that, the jQuery version became even more popular but needed to be brought up to date. This latest version uses a couple of suggestions that have been provided by commentors to improve the code. I have also added a download which contains all the code needed to run the samples.

Cascading DropDownLists or dependent dropdowns are the signature dish for AJAX applications. I spent quite a while fiddling to try to get some to work, before stumbling across a life-saving jQuery plugin that makes working with DropDownLists on the client-side a breeze. This article shows how it all works, and makes use of the WebService I introduced in my previous jQuery article.

There appear to be many articles showing how to use jQuery with ASP.NET Web Services around, but the vast majority of them illustrate the use of PageMethods that return a single value - typically "Hello World!" or the current date and time. Not much use in the real world, where you may more often need to call a service that returns a collection of complex objects. Here are a couple of examples that look at playing with more than just simple values.

Over Christmas, I had a bit of spare time, so I decided to add some functionality to this site. One of the things that I added was the ability for people to post comments about specific articles, and you will see that a form has been added at the end of this article. The other thing I have been meaning to get round to is to add a Google Site Map. I believe I have created my site to be as friendly to Google's bots as possible, but there is no harm in submitting a site map to guarantee that Google knows about all the pages I want indexed.
