RadAjaxPanel Demystified
Often I can look at one of our RadControls and know right away why using it offers a greater benefit than one of the built-in ASP.NET controls. The RadAjaxPanel is no different, but often I hear of confusion from developers as to the benefit of using this control over the built-in UpdatePanel. Well, it certainly offers the same kind of functionality as an UpdatePanel, but there's more available to you if you dig a little deeper. Basic Ajax Functionality For starters, it's important to understand how the RadAjaxPanel is meant to be used. The typical use-case scenario is when a developer has a...August 22, 2008

The Trickiest Tips in RadControls for ASP.NET (AJAX) Tests Automation
Do you wonder if there are any keys to get easy test automation over the RadControls components? I’ve seen people asking about how to get a simple (at a first glance) task done through this or that test automation tool and we generally find the specific resolution with the exact tool in use. However, in most cases the things are quite similar no matter which tool you prefer. Instead of posting particular solutions though, with this post I’m sharing some of the trickiest moments one may came across while working on tests automation of RadControls for ASP.NET (AJAX) and the ...August 21, 2008 -

RadRotator for ASP.NET AJAX: Using dynamic templates
My colleague Todd Anglin has already written a post about how to create a rotator control dynamically - you can read it here - How to Create RadRotator Programmatically. Unfortunately, this code in that post is for the old RadRotator control and if you try to use it in the new ASP.NET AJAX version, you will notice that it will not compile. Fortunately, you can quickly fix that. Here is what you need to change: FrameTemplate - this property has been replaced with ItemTemplate RadRotatorFrame - this object has been replaced with RadRotatorItem After you update the above names, you should be able...August 20, 2008

Internet Explorer JavaScript Performance Tip - use the "children" property
Today I was profiling the initialization time of RadTreeView for ASP.NET Ajax and found out that the biggest bottleneck was traversing the DOM tree. The code looks something like this: //get_childListElement() returns an HTML element var childNodes = parent.get_childListElement().childNodes; for (var i = 0, length = childNodes.length; i < length; i++) { var childNode = childNodes[i]; //Perform additional initialization } I tested with 10000 elements and in IE7 I got about 25000ms whilst in FireFox the total time was around 33ms (Core 2 Duo @ 2.33GHz). Quite a difference if you ask me. I thought that there may be some IE specific method/property which could perform better and I dug into MSDN. And a few minutes later I found the children property!!! Apparently the children collection contains only HTML elements (whilst childNodes is full of...August 14, 2008
