I made search before asking this question...

I have two listboxes... where I can select multiple rows at one time. Now I want to be able to move data to and from them. And if the user selects multiple items I want to be able to drag them all at one time.

Please point me to some articles I can read, or give me some basic explanations! I tried google for this, but came up with very little... also looked at 101 samples at msdn.


Oh, I also want the user to be able to insert them at a specific index. I think I have solved how to do that, BUT i want to give the user a graphical hint on which row the items will be dropped at... how is that possible? All I need is a line that changes when i move the mouse (with data) over the target rows, inidicating between rows 4 and 5 etc...


Anyone???
