how to keep a control value being always selected

[fanl]

Please help. I want to keep a control in the front panel being selected all the time. So when I need to update it, I can just type in new data without delete old data. Thanks.

hi
whether it is the conventional CASE structure or the EVENT structure, the working code (within the CASE) is valid.

To learn about how to use Event Structure, you might wanna look at the examples provided.
