Web: ASP.NET AJAX

One of the most-asked questions when it comes to the ASP.NET Ajax RadGrid is "How do I improve performance?". We have covered this in some Webinars and videos that can be found on Telerik TV in a series which has been released in three parts: Part One, Part Two and Part Three. One thing I wanted to bring up with respect to performance is the usage of LINQ (Language Integrated Query) and our RadGrid. Although LINQ has been out since the initial release of .NET 3.5 I still receive quite a few questions when it comes to using it with our...

Or yet another Twitter grid… Yesterday, while I was playing around with this example of our MVC Grid, I thought that the RadGrid for ASP.NET AJAX deserves one too. What I like about this sample scenario is that it gives a perfect opportunity to demonstrate both how to do client cross-site request (as we have received a few questions through our support channels) and to check the “future” ASP.NET AJAX/jQuery client-side templates prototype.     A wiser guy once said “a code sample is worth more than a 1000 words “;) That is why I’ll keep it short and let you check the...

Users can subscribe to each other and see tweets from all of their subscriptions in their main feed listings. Due to this ease of providing and receiving updates to and ...

Now that the Q1 2010 release is here, I want to bring your attention to a cool new feature in our RadCaptcha control for ASP.NET AJAX - audio support. Head on over to our online demos to see the feature in action. Enabling this on an existing CAPTCHA is easy - you just need to set the CaptchaImage-EnableCaptchaAudio property to true. Adding this feature to your site will allow blind or partially sighted people to use it as well. The audio support presents some very interesting possibilities for people who like to customize things. For example, you can replace the original audio files...
