dbgrid picklist detect when item changed or item in list is clicked

[tdb]

As per the title in a dbgrid picklist how can I detect when item changed or item in list is clicked.

Simple task is to display a list of items when the user selects an item from the list then I need to look up the id in a table and display the descriptions etc.
Note I can do this when the column is Exited but I need to do every time a new items is select (column and row stay the same).

I tried to use on EditingDone but the value retrieved is the old value not the new - Anyway to get the new value?

OnChange?!?

OnChange?!?

Thanks for the reply - I think onchange only happens after the picklist item is committed to the database.
What I need is an event that occurs after the user clicks their selection from the picklist.

On EditingDone will do what I want - Just needed so code to read the item selected from the editor - all working now.
