Ah, so you want to know how many rows could be drawn in the visible area of
the data grid. This should work:

put the dgWorkingRect of group "MyDataGrid" into theVisibleRect
put item 4 of theVisibleRect - item 2 of theVisibleRect into
theVisibleHeight
put theVisibleHeight / the dgProps["row height"] of group "MyDataGrid" into
theNumberOfVisibleRows
