Answer 4

private void listview_SizeChanged(object sender, SizeChangedEventArgs e)
{
ListView listView = sender as ListView;
GridView gView = listView.View as GridView;

var workingWidth = listView.ActualWidth - 30; // take into account vertical scrollbar
var col1 = 0.14;
var col2 = 0.14;
var col3 = 0.14;

gView.Columns[0].Width = workingWidth * col1;
gView.Columns[1].Width = workingWidth * col2;
gView.Columns[2].Width = workingWidth * col3;

}
