I guess there's no way (or maybe not) of editing a lookup field from within a dbGrid. What you should do is to add your lookup table apart and then you'll be able to change it.

What do you mean when you say I should "add your lookup table apart?"  I have a seperate table object that acts as the source for the lookup column.  I even have that mapped to some edit fields and a dbNavigator for entering new rows into that table.

Maybe my question was misunderstood.  By editable, I simply mean that I want the user to be able to type as opposed to being forced to select from the list.  I call it editable because in PB to make a "lookup" field allow typing, you set the "allow editing" property to true.  I just can't find the correct property to set in Delphi yet.

If you're using paradox, try setting the lookup field within the table properties (Table Lookup) and not within the Fields Editor.
This way you'll be able to type whatever you want but only lookup values will be accepted (but you don't have a drop down list to chose from). I've already tried and it works.

Unfortunatly, My users have standardized on MS Access.  Besides, the whole point was to have both the list and the ability to type.

Oh well, I guess Delphi is just weak in this area.  Thanks for trying thought.
