I know a lot of people have asked about this and hopefully im not being redundant. I've got an app that displays encrypted files on a USB drive in a treeview/listview combo and im trying to program functionality to double click a folder in listview and have the treevew auto expand and/or highlight the node the corresponds to the folder that was double clicked. The code is activated by a ListViewItemActivate event handler and then its supposed to call the NodeMouseClick event handler for the TreeView when i need it to load the contents of that folder into the ListView and expand the Treeview as far as that particular Node. I've gotten as far as loading the contents of the folder into the listview, thats it. it only does it for one level, meaning if i try and open another folder within the folder i just opened it will just sit. The treeview control doesn't do anything. Any info on this would be great. I know i could use some sord of combination of directoryinfo's with treenodes and things, but i already have this subroutine and i would like to keep the code tidy. Let me know if you would like the code posted.

Any suggestions?

Thanks in advance!

Hi maxl,

One very quick idea...

Both those controls allow you to add "keys" to each individual item /node within the control. So for example:

lstView.Items.Add(mykey, mydisplayvalue, 0)

and then for the treeview:

tvwTree.Nodes.Add(mykey, mydisplayvalue)

Upon the listview item click if there is one?? I can't remember.. you could just then say :

tvwTree.Nodes(mykey).Expand()

Only problem is that you (obviously) need something that's unique... like an ID number to go into these "keys".

Hope this helps!

Cheers,

Craig
