Tdbgrid and automatic post

Hello

Is it possible to "turn off" automatic posting?

This is the problem:
I use a tdb-grid which is connected to a t-query to display
data which the query "returns". I add a row to the grid, and write to it.
When I now change to another row in the grid, I don't wont the automatic
posting to take place.

Can someone help me?
