What is the difference between the onChange and onDirty events?

[Access_Novice]

Both of these are triggered as soon as you change the contents of a text box. Some website mentioned that onDirty is triggered when a form changes. So I added an option group to test that. But that option group didn't have an onDirty event.

So when would you use onChange? How about onEvent?

OnChange is an event of data controls. It executes with every character typed into the control.

OnDirty is an event of form. It executes with any data change in any control.

I have never used either of them.

I have used the form Dirty property.
If [Form_DataSoilsAgg1].Dirty Then [Form_DataSoilsAgg1].Dirty = False

I rarely use either. The change event fires with every keystroke. The dirty event fires as soon as data is changed. I typically use the before update event for validation and the after update event for handling what was entered. The appropriate event for you depends on exactly what you're trying to achieve.

Ok. Thank you all.
