now I have a TextInput and a DataGrid, now I have done the job that drag a item
from the DataGrid and drop into the TextInput.
My question is how can I determine which action is the user's last drop action. Because
user can drag and drop any times, and the data value in the TextInput will always be overwrote.
I want to save the last data value, so how can i figure this out?
Are you handling the drop manually, or using default Flex drag and drop support?
If doing it manually, wherever you are handling the drop manually, you will have to store the previous value in an array or something before updating it.
The ChikaraDev drag and drop tutorial might help:
