Developers (yours truly included) often hate it when there is a need to deal with an external tool to accomplish a simple task. The upgrade process of RadControls seems such a task – you need to start a browser, open the Telerik website, login to your account, navigate to the Downloads section, download the installer and run it.

The Column Chooser is displayed as a floating window next to the application. You can now drag...
When working with data there are a number of occasions where you may want to calculate a value for display within a grid. Did you know you can do this within the RadGridView itself?
