We have a form bound to a dataset. On one of the edit line controls we insert some event sript on the Lostfocus event. If we use RETURN 0 to terminate the event, the data changed in the control is not saved away. When we use RETURN 1, all is well. We have no other events on the control. What is the secret behind this?

The secret is that returning 0 says "I've done all the processing - don't you worry your pretty head none", whereas return 1 says "I've done my processing - now you do your stuff" - and OI's stuff includes remembering to update it's image of the data.
It's all to do with event chaining.

<QUOTE>Sedick,
On a DataSet-bound form, the system LOSTFOCUS (and POSCHANGED etc.) processing copies the data from the control into the DataSet, so if you do not RETURN 1 (or completely replace the system logic) then the DataSet will not reflect the current state of the form. I suggest using the CS_SPY window to see these changes as they occur.
On LH-bound forms, the system LOSTFOCUS (and POSCHANGED etc.) processing is responsible for setting SAVEWARN, for doing validation, conversion, required field processing, etc. So if you put a RETURN 0 on each of these events, SAVEWARN won't get set and the user won't be told to save the data. However, the manner which the data is collected to save is directly out of the controls at save time.
