So I didn't get much feedback from my post asking for help in regards to what to write, so I will go with the only suggestion I received and let you in on the upcoming features planned for the next major version of Xceed DataGrid for WPF.
So let's start with a feature that clients have been asking for since the virtualizing collection view was released: multiple selection! Yes ladies and gentlemen you will finally be able to select more than one row when using a virtualized source! Actually, the whole selection process is being revamped, so expect to see some (long awaited) changes including.... wait for it.... CELL SELECTION!
Performance! As if the grid was not already fast enough, get ready to see some performance enhancements in the standard table view!
Finally, after many many requests, the Live Explorer theme, which can be seen in the the Xceed DataGrid for WPF Live Explorer, is now included with Xceed DataGrid for WPF! Want more? How about a beautiful new Windows 7 theme? (I feel like I am on an infomercial!).

Another fantastic new addition is the print preview, which will allow users to take a look at their snazzy documents before sending them to the printer.
QTP? Did someone say QTP? You heard right! The upcoming edition of Xceed DataGrid for WPF will provide full QTP support!
Last, but definitely not least since I am most likely forgetting some, is the new group-navigation control, which replaces the previous group-navigation button, and provides quick and easy navigation between groups.
So which features are part of the Standard Edition and which ones are part of the Professional Edition? Glad you asked! Here's the breakdown:
Professional Edition Features
- Windows 7 and Xceed Live Explorer themes
- Print Preview
- Multiple selection when using data virtualization
- Group-navigation control
- QTP support
Standard Edition Features
- Improved performance in table view
