Hi all,

In case I have a dataset (get from Database and already group) so if I bind it to the Grid, Does the grid group? and How I do that? and How do I catch an event "Drag a column header here to group by that column" (sorry because I don't exactly the name of that event) to add my custom code?

(In my case, I don't want to use the default grouping of the grid because it may be slow with a huge data)

Of course I still want to use a appearance of Grid.

Thanks 

Dan
