What does and does not trigger a "Value Change Event" from an XControl?

[Mike_Le]

I have just started working with XControls. I'm trying to figure out what does and does not send a "Value Change Event" up to the parent VI.

Specifically, I have a Drop event for one of the controls nested in my XControl. I'd like this to always trigger a Value Change Event so it can be picked up by an Event Structure in the parent VI. How can I ensure that this nested Drop action inside the XControl triggers a Value Change Event to the parent?

Thanks.

Are you setting the "data changed?" boolean to true (action cluster) inside your "drop" event?

Yes, I did set the "Data Changed" boolean to TRUE inside Drop. I believe this calls the "Data Change" event inside the XControl's event structure. Does it also trigger a Value Signal up to the parent VI?
