I create a row, I add the row, I accept changes. Row never gets added to the SQL table. Am I missing a step? Doing something wrong?

Note sure how to debug this further.

cdsDataDataSet.XRefRow dr = xref.NewXRefRow();
dr.display = "Hi There";
xref.Rows.Add(dr);
xref.AcceptChanges();

The code is very ugly, and var names are garbage cause I'm just playing around trying to see how things work. But hopefully I have what you need to see here:

// ********** jobTree.cs

using System.Windows.Forms;

namespace cdsJobs
  {
  public partial class jobTree : WeifenLuo.WinFormsUI.Docking.DockContent
    {
    cdsDataDataSet dsXRef;
    cdsDataDataSet.XRefDataTable xref;
    cdsDataDataSetTableAdapters.XRefTableAdapter dsTA;

    public jobTree()
      {
      InitializeComponent();

      dsXRef = new cdsDataDataSet();
      dsTA   = new cdsDataDataSetTableAdapters.XRefTableAdapter();
      xref   = dsTA.GetData();

      cdsNode tn = new cdsNode();
      tn.Text = xref[0].display;
      tn.rec = 0;
      treeView.Nodes.Add(tn);
      }

    private void OnTreeContextMenuSelect(object sender, EventArgs e)
      {
      cdsDataDataSet.XRefRow dr = xref.NewXRefRow();
      dr.display = "Hi There";
      xref.Rows.Add(dr);
      Int32 id = xref[0].id;
      cdsNode tn = new cdsNode();
      tn.Text = "Test" + id.ToString("00000000");
      tn.rec = xref.Rows.Count - 1;
      treeView.SelectedNode.Nodes.Add(tn);
      treeView.SelectedNode = tn;
      xref.AcceptChanges();
      }
  }

  public class cdsNode : TreeNode 
      {
      public int rec = 0;
      }
}
