>>Can the grid be sorted by clicking on a column header?
Yes. The default action is to sort on a double click but that can be easily modified to handle sorting on a single click as well.
>>Is there any filtering/search mode for rows, like typing into the first row?
I am not sure if I understand exactly what you are acting. If you are asking if there is a Find and Find/Replace functionality, then yes. If you are asking whether you can filter a grid similar to a SQL query where you say show me all rows where col 2 is like xxxx, then this functionality is not in the unbound grids. You can get this type of functionality using grids bound to databases. In the unbound case, implementing a simple filter requirement would be fairly routine. It is the kind of thing our support team could probably help you with if you needed the help.
