Agree with RG. What's the point of binding it if you don't want alternate choices to update the table field? You'd have to provide more info about the process and/or design to have us suggest an alternate method, but I suspect that you've boxed yourself into a space where you don't want to backtrack and undo a bunch of work. To answer the question about a work around, what comes to mind is a temp table that you don't care what happens to the records because you'll flush it when you're done. But that brings me to RG's question...
The more we hear silence, the more we begin to think about our value in this universe.
