While working on AJAX support for r.a.d.calendar, one of our relatively new controls, I came across a very interesting issue with the ASP.NET TextBox control. The problem was related to ViewState management, or better said, the absence of such. The TextBox simply didn’t seem to handle any ViewState information and the TextBox values were not persisted and reloaded correctly after PostBack. What I was doing wasn’t rocket science - I wanted to make the TextBox (System.Web.UI.WebControls.TextBox) persist its value when the user scrolls forward or backward through the month views. My first thought was that I’m brain-dead and have had...

Over the last couple of years we've heard quite a few complaints that it's not easy to find your way around www.telerik.com and that information is scattered. I myself have been amazed how much content is there but nobody knows about it. Responding to the growing pressure from customers and our team we have been re-working our corporate site over the last few months. One part of our efforts was (and continues to be) to improve www.telerik.com structure and content. The other part of the solution was to add powerful search capabilities to our web property. Once there was a clear need for...

Tackling problems and coding solutions for them is an essential part of the job of a software engineer like myself. The only problem with this is that sometimes work becomes a little boring and repetitive. With some tasks you can even begin to feel a little like a brainless code monkey that knows how to do its job very well, but lacks the stimulation of problems that appeal to the creative capabilities of the brain. Enter the Sudoku! I have always liked logical puzzles as a kid (and adult too) and when I was first introduced to sudoku I was immediately...

Today we finally renewed our Gold Certified status in the Microsoft Partner Program. It was a bigger pain to go through all the steps and complete all requirements than it was last year, but I am very happy that everything is all set again. Now that everything is official we will be able to put the following text on our site:"Microsoft Gold Certified Partners are the elite Microsoft Business Partners who earn the highest customer endorsement. They have the knowledge, skills, and commitment to help implement technology solutions that match your exact business needs." Impressive, huh?:) Don't worry, we won't put it on...

As I have mentioned earlier (see "To leak, or not to leak…(memory) – Part One") the closures are the most common reason for memory leaks in Internet Explorer. They are extremely good at forming circular references especially in the context of Host objects. The most common example is event handlers “owned” by a Native object which are attached to a specific event raised by a DOM element and hold a reference to that DOM object kept in the Native object. Example:DOMElement.Event ->  NativeObject.EventHandler -> current execution context scope -> NativeObject. DOMElementRefference -> DOMElement Very frequently websites and web applications with a rich UI include components which produce...
