In my previous blog post I told you how the Web Service load on demand mode of RadTreeView delivers the best performance. A logical question arises - why we have the other load on demand modes (server side postback and callback) if they do not perform on par with the Web Service mode. The answer is not that obvious. The truth is every load on demand mode has its pros and cons. The following table describes visually the load on demand modes according to three criterions - performance, templates support, ease of...

I recently released the first two episodes of my new screencast series, RadTips. In these episodes I show users how to take advantage of the new client-side databinding feature of the RadGrid (only available in the Q2 2008 release of RadControls for ASP.NET). I wanted to highlight what we consider to be a best practice when using the RadGrid's client-side API to do your databinding, something I didn't do in either of the episodes.

Yeah, I know, it's been quite some time since my last post. The ideas keep coming though and I’ve just realized there is no better time for a QA to blog than ... the summer. Do you know why? Well, just because of the summer time! You know, devs are humans too and they also need to rest a bit. ;) I can at least stop bugging around for a while and post some nice, interesting content. I'm afraid the list of ideas for my future posts is already quite long. However, since I'd like to share the most fascinating ...
