c# - Force resize of GridView columns inside ListView

Question

I have a ListView WPF control with a GridView. I'd like to resize the GridView columns when the content of the columns changes.

I have several distinct data sets but when I change from one to another, the size of each columns fits the previous data. I'd like to update dynamically. How can I do that?

Finally, some results on this one. I've found a way to do the same auto-sizing that is done initially and when the gripper on a column header is double clicked.

public void AutoSizeColumns()
{
    GridView gv = listView1.View as GridView;
    if (gv != null)
    {
        foreach (var c in gv.Columns)
        {
            // Code below was found in GridViewColumnHeader.OnGripperDoubleClicked() event handler (using Reflector)
            // i.e. it is the same code that is executed when the gripper is double clicked
            if (double.IsNaN(c.Width))
            {
                c.Width = c.ActualWidth;
            }
            c.Width = double.NaN;
        }
    }
}
