As you probably know, RadControls for WinForms are built on top of our own Telerik Presentation Framework. This especially designed framework gives you the ability to extend the existing RadControls to a great level. Today, I am going to share with you how you can plug Gmail-like labels in RadGridView for WinForms (http://www.telerik.com/products/winforms/gridview.aspx).

Why new TPF improvement? Knowing that the faster an application loads, the better the overall User Experience is, we put serious efforts in optimizing our presentation framework as much as possible. Since Q3 2009, RadElement, the smallest visual unit in Telerik Presentation Framework (TPF) has been given its own lifecycle.
