    Ultimate .NET Credit Card Utility Class

    Have you ever thought about processing credit cards in your .NET application? If you have, then you know one of the first things you need to do is find some code to validate that credit card numbers entered by your users appear correct before you send them along to your payment processor. Having created applications in the past that process credit cards, I know that this task can be surprisingly harder than it should be.

    It recently came to my attention that there is no good documentation on the Telerik website showing you how to create a RadRotator (with a defined template) programmatically. There is some documentation out there showing you how to programmatically data bind a RadTicker, and the RadControls Learning Guide has some good guidance, but nothing exists online for easy Rotator reference. Let's solve that problem and take a quick look at how you can programmatically create your RadRotator and template. Step 1: Define your template. Defining a template for RadRotator in code is very similar to the process involved in programmatically creating a template...

As it name implies, Tafiti in Swahili means "do research".ShelfThe shelf is a space on the screen where you...

    XhtmlPage: What does it do?

    Have you ever been working with the Telerik Quickstart examples and wondered why all of the demo pages inherit from XhtmlPage instead of System.Web.UI.Page? Even if you guess that this custom base page somehow ensures that all rendered demo pages are XHTML valid, have you ever wondered how the base page manages to deliver that functionality? In this post, we’ll take a close look at the XhtmlPage class and see what it’s doing to deliver easy XHTML validity. The lessons learned from this class can easily be applied to your own custom page classes and used to make your web...

    ASP.NET AJAX Inheritance Gotcha

    Hello, my name is Manol Donev and I'm part of the ASP.NET team responsible for the development and maintenance of our grid, ajax, calendar, input, and chart components. With time ticking away and the September release date closing down I can assure you there is a lot going on here at the moment -- gradually orienting our ASP.NET product line towards ASP.NET AJAX is by far our main focus of course and probably you will find some of the ASP.NET AJAX tips and tricks I'll be writing about useful in your own projects as well. OK, this one does not qualify exactly...
