Column headers are not displaying...

I have included some source code below which demonstrates what I'm attempting to do.  I have derived my own ListView control from the StrataFrame base ListView control.  I am attempting to dynamically build my column headers from the business object.  All of the data is populating in the business object without a hitch, but I'm having problems with getting the column headers to display properly.

(I learned most of what I'm doing from watching what StrataFrame creates in the form designer when I enter columns manually, etc.)

Any ideas where I might be going wrong?

public virtual void FillRows(MicroFour.StrataFrame.Business.BusinessLayer bo, string dataRetrievalMethodToExecute)
{
// set initial properties
base.SuspendLayout();
base.ListPopulating += new MicroFour.StrataFrame.UI.Windows.Forms.ListView.ListPopulatingEventHandler(OnListPopulating);
base.RowPopulating += new MicroFour.StrataFrame.UI.Windows.Forms.ListView.RowPopulatingEventHandler(OnRowPopulating);
base.AutoColumnSort = true;
base.AutoNavigateToSelectedRecord = true;
base.FullRowSelect = true;
base.GridLines = true;
base.View = View.Details;
// set up the business object
base.BusinessObject = bo;
// set up columns automatically
MicroFour.StrataFrame.UI.ListViewPopulationColumn OHRLVPopCol;
int i = 0;
string[] displayFields = bo.AllFieldsList.ToArray();
foreach (string field in displayFields)
{
base.Columns.Add(new ColumnHeader());
OHRLVPopCol = new MicroFour.StrataFrame.UI.ListViewPopulationColumn();
OHRLVPopCol.FormatString = "{" + i++ + "}";
OHRLVPopCol.PopulationType = MicroFour.StrataFrame.UI.ListViewColumnPopulationType.FormattedString;
OHRLVPopSettings.FormatColumns.Add(OHRLVPopCol);
}
OHRLVPopSettings.DisplayFieldNames.AddRange(displayFields);
OHRLVPopSettings.BusinessObjectType = bo.GetType().ToString();
OHRLVPopSettings.DropDownFormatString = "";
OHRLVPopSettings.FormatString = "{0}";
OHRLVPopSettings.MethodToExecute = dataRetrievalMethodToExecute + ";";
OHRLVPopSettings.ValueMember = bo.PrimaryKeyField;
base.PopulationDataSourceSettings = OHRLVPopSettings;
// fill the list view with x number of records 
base.Requery();
base.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);
base.ResumeLayout();
// select the first element in the list view
if (Items.Count > 0)
Items[0].Selected = true;
}

I figured this out.  Instead of doing 
base.Columns.Add(new ColumnHeader());
within my loop, I am now doing 
base.Columns.Insert(i, displayFields[i]);
and my column headers are appearing exactly as I want them to.
