Thank you
I don't see any row highlighted. I've checked that the treeview is not
empty when I use the code:
log4net.Info("number of rows highlighted: " +
this.Selection.CountSelectedRows() -> 1
this.Model.IterNChildren() -> 3

If I click on the first item, or if I push the bottom arrow key, then
the first row is highlighted.

I've also tried to highlight all the rows:
this.Selection.Mode = SelectionMode.Multiple;
this.Selection.SelectAll();

The value of this.Selection.CountSelectedRows() is 3, but I still don't
see any highlight!
