Subject Re: How to calulate field value in a Grid?

Is it a calculated field or a field from table. If a calculated field then it will be changed automatically. If from table then check the next point. (If it is a calculated field then the rowset will probably be readonly) How is Estimated_date changed. If it is in grid then I have no idea. Never did such programming for editing in Grid. If  you are changing in entryfield then use the onLostFocus event of the entryfield to change the value. Regards Akshat
