I think there is a real need to try and get the ui feeling much more like a desktop app with regards to how data is added to a grid - I have always found the Telerik Ajax grid to be overly cumbersome for entering new rows of data. There needs to be a fluent approach to this  where by tabbing through all of the columns in the last row in the grid it should add a new row that can quickly be updated again via tabbing - much like win form controls; the aim should be speed and ease of use.
