When in batch edit mode, using standard asp.net validation controls will display the validation error within the cell, and expand the cell contents horizontally and possibly vertically as well. This is a very ugly (and clunky) way to show validation messages in a batch edit mode. It would be nice if instead, we could set an grid attribute that specifies a row backcolor when validation fails for a row. In addition, show that rows validation messages automatically in a tooltip or radtooltip as the user hovers the mouse over the row when it signifies the exception backcolor. These messages could be assigned to a columns markup as an attribute. Another nice to have is to show a section on the grid (perhaps under the header) that could display to alert the user when validation had failed.
