>>I want to display text in a text box in a column of a grid. The value displayed depends on the value in another field in the grid control source table. I tried putting code in the text box When method to calculate the value and assign it to THIS.VALUE. This works OK when I click on the text box, but if I scroll the grid all of the records change to the value in the currently highlighted record. Where do I need to put the code to make each record dis[lay the correct value for each record?
