I have a header/detail form with a grid for the detail part. One of the data field in the grid is a logical field and I use a checkbox to display its contents. However, when I click on the checkbox to set its value to true and i move to the next column, the check box looses its value (goes back to false). Why is this? How can I get this to work right?

If I use a textbox instead of a check box, and I enter the value "T" - true -it keeps the value of true when I move the the next column.

Thanks in advance
