tree view hide key

[Bob Sneidar]

You and others have addressed a lot of the work I think, and thank you for that by the way. One of the things I would like to see is something akin to findRecord and findIndex in a datagrid. Of course, finding something several levels in requires that you would need to return not just a number, but a root node with the path to the found item, so you can reference it in the future, getting and setting anything in the "path". 

I wanted to create a list of items with a name and value, but then I realized I wanted to rearrange them, moving them up and down in the list. I also wanted to be able to double-click an item and put the value into another field. I call the feature "QuickNotes" where I have a pallette like stack I can double click text snippets to fill in a field with text I type often, as in a copier installation. 

In the end I used a datagrid so no big deal, but it left me wondering why I would ever use a tree view. But as you mentioned a lot of work is being done on it now. I cannot switch over to 9.1 yet because I made a custom change in the datagrid behavior which allows me to nest behaviors, so until that gets bundled into a release I cannot test any new changes (at least not with my current project).
