RadComboBox for ASP.NET AJAX is the successor of RadComboBox for ASP.NET. The next generation of RadControls is built entirely on top of ASP.NET AJAX, utilizing its common client-side framework and programming model. RadControls for ASP.NET AJAX introduce a number of new features and performance optimizations, which are hard or impossible to implement in the regular ASP.NET suite. The integration and API models of the controls are also better, due to the common framework they share (RadControls for ASP.NET AJAX are shipped as a single assembly - Telerik.Web.UI.dll.) It is important to note that this new generation of RadControls will work on ASP.NET 2.0, 3.5 and above because of the underlying ASP.NET AJAX framework.
Although there are a lot of new features in RadComboBox for ASP.NET AJAX some of the functionality from the “classic” ASP.NET version is still the same. The forum threads in the RadComboBox for ASP.NET forum
- DesignTime work with the control
- Server-side object model and event handling
