Multicolumn listbox dblclk property

Recommended Posts

Hello guys.

I'm using Labview for one year. I've played with lots of stuff including Database Connectivity toolkit. I'm stuck in something that maybe simple. I have a multicolumn listbox and i want to manage it's data. I want to add (no problem), edit/replace and delete. To perform the last two actions (edit or delete) i must know the row the user clicked and feed the replace array or the delete array VI. So i use the Get DblClk row method. My problem is that i always get -2, which means the user has clicked on a empty row. I'm using event programming to reduce polling.Everything is working fine, but this. Which event must i associate with this method? I have also created a simple vi with one multicolumn listbox inside a loop (no events at all). The same happens. What am i doing wrong?

The online help....doesn't help at all!!

Well, if the user double-clicks on a row, the selected value should be able to be accessed.

To get the value on a double click, you'd have to have it recognize the double click as an event to generate the event, then just get the value they selected, not the double-click value. The row would be selected on the 1st click anyway... right? I might be missing something though. I haven't used double-clicking much.

You shouldn't be getting -2 for row or value. Here are a couple of pictures that may help.

Yes!!!!!!! God, how blind I am!!!!!! I was seeing the ROW terminal on the left of the double click event, but i was not thinking at all "What is this? Maybe I should use it."

Thank you very much, todd, for opening my eyes. :) )))
