I have a gridview with template items and am binding the gridview with a data table. What is happening is that the columns with the textboxes, etc are populating, but then extra columns from the data table with the same data is being added to the end of the gridview. code is attached. I tried to clear the gridview, but it got rid of the template item fields.
aspx.cs

protected void Page_Load(object sender, EventArgs e)
        {
            //forces postback when the treeview iten's check box is clicked.
            tvContracts.Attributes.Add("onclick", "postBackByObject()");

            ManagedUser = (Administrator)HttpContext.Current.Session["UserObject"];

            //Populating all drop downs for the contract modal window.
            if(!IsPostBack)
            {
CallOptions.fillEmptyCallOptionGV(CallOptionGV);
            }
        }


calloption.cs

public void fillEmptyCallOptionGV(GridView GV)
        {
            dt = new DataTable();

            dt.Columns.Add("NAME");
            dt.Columns.Add("CALL_OPTION_NAME");
            dt.Columns.Add("COUNTERPARTY_NOTIFICATIONS");
            dt.Columns.Add("EMO_NOTIFICATIONS");
            dt.Columns.Add("COUNTERPARTY_EMAILS");
            dt.Columns.Add("EMO_EMAILS");
            dt.Columns.Add("TRADES_DEAL_NUMBER");
            dt.Columns.Add("DEFAULT_TO_AVAILABLE");
            dt.Columns.Add("POR_AVAILABILITY");
            dt.Columns.Add("MW");
            dt.Columns.Add("ALLOW_ADDITIONAL_MW");
            dt.Columns.Add("SELLER_AVAILABILITY_BY");
            dt.Columns.Add("EMO_STRIKE_NOTICE_BY");
            dt.Columns.Add("MIN_RUN_TIME");
            dt.Columns.Add("MIN_DOWN_TIME");
            dt.Columns.Add("STARTS_PER_DAY");
            dt.Columns.Add("EMO_INTRADAY_CHANGES_BY");
            dt.Columns.Add("MIN_CONTRACT_STARTS");
            dt.Columns.Add("MAX_CONTRACT_STARTS");
            dt.Columns.Add("ADDITIONAL_START_CHARGE");
            dt.Columns.Add("COMMENTS");
            dt.Columns.Add("ID");

            dt.Rows.Add(new object[] { "A", "", "0", "0", "", "", "", "1", "", "", "", "", "", "", "", "", "", "", "", "", "", "1" });
            dt.Rows.Add(new object[] { "B", "", "0", "0", "", "", "", "1", "", "", "", "", "", "", "", "", "", "", "", "", "", "2" });
            dt.Rows.Add(new object[] { "C", "", "0", "0", "", "", "", "1", "", "", "", "", "", "", "", "", "", "", "", "", "", "3" });

            GV.DataSource = dt;
            GV.DataBind();

        }

You need to add AutoGenerateColumns="false" to your gridview definition in order to stop it auto-creating them.

Set the AutoGenerateColumns attribute to false :

<asp:GridView ID="CallOptionGV" runat="server" BackColor="White" Width="1200" OnRowDataBinding="CallOptionGV_RowDataBound" DataKeyNames="ID"
        BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" CellPadding="4" Font-Size="Small"
        ForeColor="Black" GridLines="Vertical" AutoGenerateCoumns="False">
