reorder listbox

[faustina]

I created a VI in LV 7.0 with a multicolumn listbox that the users were able to reorder the contents using drag-drop.  I never processed any events for this control.  This control still works in the same manner in LV 8.5.1.  However, if I copy this control to a new VI I can no longer reorder the contents using drag-drop.  So why the change in behavior?

That could not have happened at all, because LV 7.0 did not support drag & drop events.

Only from LV 8.x, that too, 8.5 I think, that drag & drop events are supported thro' event structures.

Maybe, if you can post the VI here, someone can help you out...

Seems to work fine here:

1. Create an MC listbox in 7.0.
2. Enable dragging (right click>>Selection Mode).
3. Save the VI.
4. Open in 8.5.1.
5. Run it. It works.
6. Copy the listbox and paste in a new VI.
7. Run it as well. It still works.

There are two things you should check - 

1. For the dragging to work you either have to have the VI in run mode (by running or pressing ctrl+M) or to grab the row at exactly the right point (on the row seperator, when the cursor changes).
2. The item dragging must be enabled.
