Hilmar,
I found out the reason why it is happening. But don’t no the remedy.

I created 2 text boxes on the same form. 1st with the ControlSource as temp201.STOCK_NO (temp201 is the RecordSource for the grid) and another with ControlSource as value in the grid for the column STOCK_NO. If I change the row when I am in the first column, that is STOCK_NO, both the text boxes show the correct value of the record where I am. If I do so from any other column, 2nd text box value does not change. I tried this in another test form also, where AfterRowColChange for the grid says THISFORM.REFRESH(). There is no other code. There also it is doing the same thing.

You said, I need to refresh all the controls except grid. How can I do so? Will that solve this problem?

Many Thanks,
Yashodhan
