Oscar,

The left pane of the Windows explorer is TreeView and the right pane is ListView. I guess you are after ListView not TreeView.

>I'm looking for a treview with column headers like the ones contained by the windows explorer sreen where you can click on one of them to change the data ordering and also to adjust the width.

>My customer showed me an application named Oros Book where this kind of tree view is used extensively.
>
>Thanks in advance for any hints.
