Improve the DataGrid control to support dynamic group.
For dynamic group, instead of client side group by, I mean every time a group by column added or removed,a real remote data refresh should be considered.
This is extremely useful for end user so they can group by whatever columns they want, which can be considered a dynamic reporting viewer.

Add support for group by hints. For example, an order table has an OrderDate field, user can group by OrderDate, but that doesn't make much senses, there should be an combobox shows all hints apply to Date type, such as Year,Month, Day, Date, MonthOfYear, DayOfWeek etc. This will make the group by really powerful and useful.
