Thank you Mr. Jim Booth
The control source for each edit box is different. I have checked many times. This problem is coming only in Editbox for text box it is ok. I drag container class and that class is very simple there is nothing just only container and edit box and label (just to save the time i add this class).
After InteractiveChange event of Option group each value in editbox is coming ok. But when I select edit box to change, its value replaces with last value, which I have mention for the last edit box in InteractiveChange event of Option group. I have tried the same option group for text box instead of edit box. And text box in container is working good, there is no problem on selection of any text box.
Due to memo field I have to use edit box.
And in the do case there is no any extra enddo.
Thanks
