Hi,

Try something like this:

// Define Column numbers

enum Column {
	One,
	Two
}

// Setup Treeview

treeview1.HeadersClickable = true;

TreeViewColumn tv = new TreeViewColumn ("Column 1", new CellRendererText
(), "text", (int)Column.One);
treeview1.AppendColumn (tv);
tv.SortColumnId = (int)Column.One; // This do the trick!

tv = new TreeViewColumn ("Column 2", new CellRendererText (), "text",
(int)Column.Two);
treeview1.AppendColumn (tv);
tv.SortColumnId = (int)Column.Two; // This do the trick!
