Hi,
What would be the best method of detecting that the user has changed the content of a control on a page. Let it be 1 or more controls.
This would be to detect that the user has changed something in order to ask if he wants to save the data when he navigates away or selects another record to be loaded when the previous one is not saved yet.
I was wondering if I could do this without having to call a "DataHasChanged" function in every control's OnChange event ?
Thanks
Danny |

Hi Danny
the easy way to do that is to use the ..modified property of the page or of the list of controls (with enumxxx and indirections)
However, if a control was changed from John to Johns THEN BACK to John, ..modified will STILL be true
So the ONLY way to do that perfectly is to store the original values, and compare with enumxxx and indirections
Best regards |

Fabrice,
Thanks for the anwser, but I cannot seem to find the ..Modified parameter. I checked the help and these functions do not seem to be available for Webdev.
So I'll have to find another way.
Thanks
