Enum drop down select event

[miguelc]

I would like an event to be fired each time the user selects a selection from the drop down list of an enum. I know I can use the Value Change event, but I want the event to fire also when the user selects the same selection as the last time (which Value Change event does not fire on). I've tried the Mouse Up event but it seems to not fire when the Mouse Up is on the drop down list. Any ideas?

Hi Michael,
you can use the mouse down menu. If this is not enough, can you please explain what you try to do?

I don't understand what you mean by the mouse down menu, I don't see that anywhere in the list of events in the Event structure for an Enum. I've attached a VI explaining a little more. I can't use a Mouse Down event because that fires before the user is able to selet an item from the drop down list.

Hi Michael,
i meant the mouse down event. If you want that an event occurs if the user selects a new value or an old value, i don´t understand why you can´t use the mouse down event. Can you explain it please?

Have you run the VI I attached in the last message? If you use the Enum that says Mouse Down, you will see that when the user clicks on the enum, the mouse down event fires right away without allowing the user to select from the drop down list. If I'm missing something please let me know, or better yet show me with code.

Hi Michael,
yes i saw your vi and a run it. Can you please explain what you try to do, i´m not really understand why you need the event if the value not change.

Thanks

Maybe this is a lost cause... What I wanted to do was have an Enum (or combo box, whatever) with a list of different Import options a user could do. They would press the Enum, and select the type of import from the drop-down list. As stated previously, a Value Change event would work fine for this, except that it doesn't fire when the same item is selected a second time without a change in between. This is a problem since the user could easily want to perform the same kind of import many times in a row.

I may have to just add a button next to the Enum, and have the user select from the Enum, then press the button to fire the event. Oh well.

This may not be exactly what you had in mind but it does work ok, for a workaround.  I basically reset the value of the enum after the selection.  I added a status indicator to display the last action taken.  I hope this helps.

Hi Michael,

Did you try the Mouse Leave event? Just a thought...

Not only Mouse Leave, also Mouse Enter & Mouse Move do not work for your cause.
