I have a datagrid that is created at run time

  DataGrid dgG = new DataGrid();
  BoundColumn bcB;

  dgG.CellPadding = 5;
  dgG.CellSpacing = 0;
  dgG.GridLines = GridLines.Both;
  dgG.CssClass = "SectionTableLines";
  dgG.DataKeyField = "PlanWorkOrderID";
  dgG.ID = DataSetName + "." + Constants.datagrid + "." + "0";

  dgG.HeaderStyle.CssClass = "SectionHeader";

  bcB = new BoundColumn();

  bcB.DataField = "WorkOrder";
  bcB.HeaderText = "WorkOrder";
  dgG.Columns.Add(bcB);

  dgG.AutoGenerateColumns = false;

  EditCommandColumn eccE = new EditCommandColumn();
  eccE.EditText = "Edit";
  eccE.CancelText = "Cancel";
  eccE.UpdateText = "Update";
  eccE.HeaderText = "Edit";
  eccE.ButtonType = ButtonColumnType.LinkButton;
  eccE.ItemStyle.CssClass = "TxtBox";

  dgG.Columns.Add(eccE);
  dgG.EnableViewState =false;

  ButtonColumn btncBC = new ButtonColumn();
  btncBC.HeaderText = "Delete";
  btncBC.ButtonType = ButtonColumnType.LinkButton;
  btncBC.Text = "Delete";
  btncBC.CommandName = "Delete";

  dgG.Columns.Add(btncBC);

  dgG.DataSource = dtT;
  dgG.DataBind();

  dgG = qabQA.makeWorkOrder(dstForm1370.Tables[Constants.WorkOrder]);
  dgG.EditCommand  += new DataGridCommandEventHandler(dgG_EditCommand);
  dgG.DeleteCommand += new DataGridCommandEventHandler(dgG_DeleteCommand);
  dgG.UpdateCommand += new DataGridCommandEventHandler(dgG_UpdateCommand);
  dgG.ItemCommand  += new DataGridCommandEventHandler(dgG_ItemCommand);
  dgG.CancelCommand += new DataGridCommandEventHandler(dgG_CancelCommand);
  tcC.Controls.Add(dgG);  // tcC is a table cell

The event handlers are the standard stuff.

 private void dgG_EditCommand(object source, DataGridCommandEventArgs e)
 {
  Control ctlC;
  string sDGID;

  sDGID = Constants.WorkOrder + "." + Constants.datagrid + "." + "0";

  ctlC = FindControl(sDGID);

  ((DataGrid)ctlC).EditItemIndex = e.Item.ItemIndex;

  BindGrid();

 }

 private void dgG_DeleteCommand(object source, DataGridCommandEventArgs e)
 {
  DataTable dtT;
  int dgPK;

  dtT = dstForm1370.Tables[Constants.WorkOrder];
  dgPK = (int)e.Item.ItemIndex;
  dtT.Rows[dgPK].Delete();

  BindGrid();
 }

 private void dgG_ItemCommand(object source, DataGridCommandEventArgs e)
 {
  DataTable dtT;
  int dgPK;

  if (((LinkButton)e.CommandSource).CommandName == "Delete")
  {
   dtT = dstForm1370.Tables[Constants.WorkOrder];
   dgPK = (int)e.Item.ItemIndex;
   dtT.Rows[dgPK].Delete();

   BindGrid();
  }
  else
  {
  }
 }

 private void dgG_UpdateCommand(object source, DataGridCommandEventArgs e)
 {
  DataTable dtT;
  string sDGID;
  int iPK;

  dtT = dstForm1370.Tables[Constants.WorkOrder];

  sDGID = Constants.WorkOrder + "." + Constants.datagrid + "." + "0";

  iPK = (int)e.Item.ItemIndex;

  dtT.Rows[iPK]["WorkOrder"] = ((TextBox)(e.Item.FindControl(sDGID))).Text;

  BindGrid();
 }

 private void BindGrid()
 {
  DataTable dtT;
  Control ctlC;
  string sDGID;

  dtT = dstForm1370.Tables[Constants.WorkOrder];

  sDGID = Constants.WorkOrder + "." + Constants.datagrid + "." + "0";

  ctlC = FindControl(sDGID);

  ((DataGrid)ctlC).DataSource = dtT;
  ((DataGrid)ctlC).DataBind();
  Session["Form1370DataSet"] = dstForm1370.Copy();
 }

 private void dgG_CancelCommand(object source, DataGridCommandEventArgs e)
 {
  Control ctlC;
  string sDGID;

  sDGID = Constants.WorkOrder + "." + Constants.datagrid + "." + "0";

  ctlC = FindControl(sDGID);

  ((DataGrid)ctlC).EditItemIndex = -1;

  BindGrid();

 }

The Editcommand column renders properly on screen. When I click the Edit
Link button, it correctly fires the Edit event which calls my EditGrid
method and puts me in edit mode. So far, so good. But, when I click the
update button or the cancel button, it fires the Edit event again instead of
firing Update or Cancel events. In other words, no matter what button I
click, it always puts me in my EditGrid method. I don't know why.

I found one other person who had the exact same problem.  The advise was:

I think your problem may be in the page_load subroutine. Make sure you don't
bind any data to the at a grid there unless IsPostBack is false (the first
time you go there should be the only time data is bound to the grid). I
think when you hit the Update link, it goes to the page_load sub before it
does anything else. Thus, if you bind data there to the datagrid, you just
bind what you already have--not the changes you want to make.

I do not think that applies to me.  Here is my page_load event handler

 private void Page_Load(object sender, System.EventArgs e)
 {
  DataAccess objDA;

  if (Page.IsPostBack)
  {
   dstForm1370 = ((DataSet)Session["Form1370DataSet"]).Copy();
   BuildSections(); // data bind when grid created
  }
  else
  {
   objDA = new DataAccess();
   objDA.PlanID = Convert.ToInt32(Session["PlanID"]);
   dstForm1370 = objDA.GetDataSet("Form1370Data");

   BuildSections(); // data bind when grid created

   Session["Form1370DataSet"] = dstForm1370.Copy();
  }
 }

I am at a loss.  Anyone have any suggestions?

Thanks.
