Hi, I want to know how to read the text in a uniedit or unicombobox during editing when used in a column in unidbgrid.
Using extEvent don't give me text  except for the event "data" useful for remote queries.
I need to manage and change edit text when data is no present in remote query, but ther is no possibility in dbgrid's unicombobox..... 
There are ways for manage events in controls embedded in grids?
