People keeps complaining that web grids are slower and more difficult to use than Excel. We definitely need a radgrid control with excel-like editing. Ideally we need the look-and-feel of the radspreadsheet, with the fixed columns of the radgrid, the events for updating a database, and maybe direct databinding to a database table. What they want to see is Excel. Like the MS-Access UI, when they move (with keyboard) from row to row, they expect the database to get updated accordigly.
