Question

Ive got a custom listview class like this one:

class ListTreeView : ListView
{
    //some stuff
}

Is there a way to override columns.add(string text); like i can do with Refresh()

public override void Refresh()
{
    //some stuff
}

‘No’

If a method is declared Virtual, then Yes. But unfortunately in your case its a No because ColumnHeaderCollection can’t be overridden.
