DataGrid: some questions

You can tell if the user clicked in the header by checking "the dgHeader of
the target" - it will be empty if the user did not click on the header, the
long ID of the group containing all the column headers if the user clicked
on the header.  If the user clicked on a specific column header rather than
the empty area of the header to the right of the columns, the
dgHeaderControl of the target contains the long ID of the column header
control.

Never thought about detecting a click in the scrollbar, not sure how you
would rule that out.

Personally,I prefer to provide a button for the user to click on to add a
new row of data to a datagrid, just seems more user friendly to provide a
visual clue as to how to add a row than leave the user to guess that a
double click in an empty row of the datagrid is the way to do it.  With the
button approach, you avoid having to scroll through a bunch of rows to get
to the end of data and see an empty row, in fact there won't be an empty row
if the total number of rows of data is an exact multiple of the number of
visible rows in the datagrid.
