Hiding column in ASP datagrid

[mpriem]

Hi,

I am trying to hide a column in a datagrid I dynamicaly created, but
fail to with the following code:

....
....
foreach(XmlElem ent objStorageGroup in objServer.Child Nodes)
{
this.intMbSG = 0;
this.objDataGri d =
this.GetDataGri d(objStorageGro up.Attributes["Name",""].Value);
this.objDataGri d.Font.Bold = true;
this.objDataGri d.BackColor = System.Drawing. Color.Gray;
this.objDataGri d.ForeColor = System.Drawing. Color.White;
this.objDataGri d.HeaderStyle.H orizontalAlign = HorizontalAlign .Center;
this.PlaceHolde r1.Controls.Add (this.objDataGr id);
this.objDataGri d = new DataGrid();
this.objDataGri d.ItemDataBound += new
DataGridItemEve ntHandler(objDa taGrid_ItemData Bound);
this.objDataGri d.ItemCreated += new
DataGridItemEve ntHandler(objDa taGrid_ItemCrea ted);
DataTable objTable = new DataTable();
objTable.Column s.Add(new DataColumn("Sto re Name",typeof(st ring)));
objTable.Column s.Add(new DataColumn("Mai lboxes",typeof( string)));
objTable.Column s.Add(new DataColumn("Quo ta",typeof(stri ng)));
foreach(XmlElem ent objStore in objStorageGroup .ChildNodes)
{
DataRow objRow = objTable.NewRow ();
objRow[0] = objStore.Attrib utes["Name",""].Value;
objRow[1] = objStore.ChildN odes[0].Attributes["Count",""].Value;
objRow[2] = objStore.ChildN odes[1].Attributes["Count",""].Value;
objTable.Rows.A dd(objRow);
this.intMbSG = this.intMbSG +
Convert.ToInt32 (objStore.Child Nodes[0].Attributes["Count",""].Value);
}
this.objDataGri d.DataSource = new DataView(objTab le);
this.objDataGri d.DataBind();
this.objDataGri d.Columns[2].Visible = false;
this.objDataGri d.Width = 500;
this.objDataGri d.Font.Name = "Verdana";
this.objDataGri d.Font.Size = 10;
this.objDataGri d.HeaderStyle.F ont.Bold = true;
this.objDataGri d.BackColor = System.Drawing. Color.DarkOrang e;
this.objDataGri d.ItemStyle.Bac kColor = System.Drawing. Color.White;
this.objDataGri d.AlternatingIt emStyle.BackCol or =
System.Drawing. Color.White;
this.PlaceHolde r1.Controls.Add (this.objDataGr id);
this.objDataGri d = this.GetDataGri d("Mailboxes in Storage
Group",this.int MbSG);
this.PlaceHolde r1.Controls.Add (this.objDataGr id);
this.intMbServe r = this.intMbServe r + this.intMbSG;
}
....

It crashes on : this.objDataGri d.Columns[2].Visible = false; >> Index
out of range.

What am I doing wrong???

Thanks in advance!!!
