How do I determine which Flex AdvancedDataGrid cell - row and column index - I've just dropped onto? calculateDropIndex seems to give me the row, but how do I get the column?
It is going to be a pseudo code:
on drop:
get x coordinate local to that grid when dropped
loop over visible grid columns while adding their widths
stop when total widths is greater than x coord
and there should be your column.
Does that help?
