I have am having a problem hiding child rows of my self referencing table which are appearing in the root band.  I am handling the InitializeRow event and am checking to see if they should be children or root rows.  If they are children, I set e.Row.Hidden = true.  When running the application no rows are hidden.  If I set a break point in the event handler, then the rows will be hidden.  This seems very odd to me  can anyone give me some pointers on how to make these rows hide properly?  I am using 20083.2115.

Sample code below.

public Form1() {

  InitializeComponent();

  DataSet ds = new DataSet();

  DataTable dt = new DataTable();

  DataColumn dc = null;

  DataRow dr = null;

  dc = new DataColumn("ID", Type.GetType("System.Int32"));

  dt.Columns.Add(dc);

  dc = new DataColumn("ParentID", Type.GetType("System.Int32"));

  dt.Columns.Add(dc);

  dr = dt.NewRow();

  dr["ID"] = 1;

  dr["ParentID"] = DBNull.Value;

  dt.Rows.Add(dr);

  dr = dt.NewRow();

  dr["ID"] = 2;

  dr["ParentID"] = 1;

  dt.Rows.Add(dr);

  dr = dt.NewRow();

  dr["ID"] = 3;

  dr["ParentID"] = 1;

  dt.Rows.Add(dr);

  dt.TableName = "SelfReferencingTable";

  ds.Tables.Add(dt);

  ds.Relations.Add(ds.Tables["SelfReferencingTable"].Columns["ID"], ds.Tables["SelfReferencingTable"].Columns["ParentID"]);

  this.ultraGrid1.DisplayLayout.MaxBandDepth = 5;

  this.ultraGrid1.DataSource = ds;

}

private void ultraGrid1_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e) {

  // if i set a break point here, the rows will be hidden correctly

  // without a break point or simply running the .exe will not hide any rows

  if (e.Row.Band.ParentBand == null) {

    if (e.Row.Cells.HasCell("ParentID") && e.Row.Cells["ParentID"].Value != DBNull.Value) {

      e.Row.Hidden = true;

    }

  }

}
