Solved!
Go to solution

Hi,

 

There seems to many posts on deleting rows from multicolumn listbox programmatically but not from single column listboxes.

Woth the help of Blokk and 

Make an array of the items clicked in a list

Have an array of strings for the 'ItemNames' that go into the listbox and store it on a shift register. When you delete an item (e.g. from an event case), remove that item from the list (using delete from array) and write it back to the ItemNames property of the listbox. A single column listbox works in exactly the same way as a multicolumn listbox.

Thank you so much Sam_Sharp. You've given me more insight into how to use Listbox.

 

May I ask why do you have the error out connected to the while loop?

It's not really necessary - but it's just there to make sure that the property node executes (and writes the items to the listbox) before the while loop starts (dataflow!).

Use the Code Capture Tool rather than NI's built in VI snipped option and you won't have that problem.

Yes, although I have noticed that NI did apparently fix these issues with LV 2015 (but the CCT still has some advantages, like including the FP in the image or backsaving the snippet).
