Explained: RadGridView for WinForms virtualization and its implications. The case with CellElement and RowElement
As the Logical vs. Visual Grid Structure help article states, RadGridView for WinForms uses virtualization for its cells/rows and as of Q2 2010 there is column virtualization as well. What is virtualization? To put it simply, when you bind RadGridView to a DataTable with 1000 rows, you get 1000 data row objects created in RadGridView (of type GridViewDataRowInfo). However, not all data row objects can be visible at the same time in the RadGridView estate in your application.

New goodies in RadGridView for WinForms: Drag and drop with RadGridViewDragDropService
One of the new goodies that came with RadGridView Q2 2010 is the brand new drag and drop API, which offers a very flexible way to create custom drag and drop scenarios with ease.

Export Beyond Excel with RadGridView for WinForms
The RadControls for WinForms Q2 2010 beta release has been live for a couple of weeks now, and we have been getting excellent feedback on the fancy new features. Along with several brand new components (RadListControl, RadPageView and RadDesktopAlert to name a few), we have introduced a completely redesigned grid, along with numerous new features and possibilities. Up until now we have supported Export to Excel capabilities in RadGridView, and not much more. Although ExportToExcelML offers some cool and unique features, exporting only to Excel was not enough for our clients. Our integration with Telerik Reporting could not suit all of our client's requirements either. Now,...
