I have designed an aspx page in which i am having a gridview.
I used SQL server as backend and my database database name is "sample"
I created a stored procedure to select employee name from "emp" table from "sample" database and filled it to a dataset.
I had filled that gridview with that dataset and loaded employee names and Id.
I want to append a Datatable that contains only one static row into the same dataset.

If data inside "emp" table is

empId empName

1 Subha
2 Harshini

Then, during page load, along with these 2 rows, a third row as,

3 New

should be added to dataset.The output should be as below.

empId empName

1 Subha
2 Harshini
3 New

The source code I used is shown below.

In Grid.aspx.cs, the following code is used.

protected void GridView1_PreRender(object sender, EventArgs e)

        DataSet ds = new DataSet();

        ds = obj.select();

        GridView1.DataSource = ds;

        DataTable dt = new DataTable();
        DataRow dr;
        dt.Columns.Add("id", System.Type.GetType("System.Int32"));
        dt.Columns.Add("name", System.Type.GetType("System.String"));
        dr = dt.NewRow();
        if (GridView1.Rows.Count == 0)
            dr["id"] = Convert.ToInt32("1");
            dr["name"] = "New";
            int ct = GridView1.Rows.Count;
            int hid = Convert.ToInt32(GridView1.Rows[ct].Cells[0]);
            dr["id"] = hid + 1;
            dr["name"] = "New";

        dt = ds.Tables[1];
        GridView1.DataSource = ds;
        for (int i = 0; i < GridView1.Rows.Count - 1; i++)
            LinkButton ln = new LinkButton();
            ln = (LinkButton)GridView1.Rows[i].Cells[2].FindControl("l1");
            ln.Visible = false;

In hol.cs,select method is used.

using System.Data.SqlClient;
using Majestic.Common;
public class hol:Common
    public DataSet select()
        DataSet ds = SqlHelper.ExecuteDataset(con, CommandType.StoredProcedure, "uspselect");
        return ds;

Note: Majestic.Common dll is used for database connectivity and manipulations.

In Grid.aspx page, I used the following code inside <body> tag.

    <form id="form1" runat="server">
        <asp:GridView ID="GridView1" runat="server" OnPreRender="GridView1_PreRender" AutoGenerateColumns="false">
        <asp:TemplateField HeaderText="Id">
        <asp:TemplateField HeaderText="name">
        <asp:LinkButton ID="l1" runat="server">New</asp:LinkButton>



Can you tell if it is possible?If so, kindly give me the source code and also the guideline to solve this problem.

Thank You,
Subhashini Palanivel.
