What I have tried:

Here is my aspx.cs code

C#

protected void Page_Load(object sender, EventArgs e)
 {
   load();
  }
  public void load()
  {
           SqlConnection cnn = new SqlConnection("Data Source=HAMEED_KHAN\\SQLEXPRESS;Initial Catalog=db_compiler;Integrated Security=True");
           string query = "SELECT Column_Name FROM tbl_field WHERE Table_Name='std'";
           SqlCommand cmd = new SqlCommand(query, cnn);
           cnn.Open();
           string somevalue = cmd.ExecuteScalar().ToString();
           DataTable dt1 = new DataTable();
           SqlDataAdapter da = new SqlDataAdapter(cmd);
           da.Fill(dt1);
           cmd.ExecuteNonQuery();
           int rows = dt1.Rows.Count;
           DataRow dr = null;
           foreach (DataRow row in dt1.Rows)
           {
               DataTable dt2 = new DataTable();
               dt2 = new DataTable();

               for (int i = 0; i < rows; i++)
               {
                   dt2.Columns.Add(dt1.Rows[i][0].ToString(), System.Type.GetType("System.String"));

                   dr = dt2.NewRow();

               }


               Session["MyDataTable"] = dt2;

               DataTable dt3 = (DataTable)Session["MyDataTable"];

               DataRow row1 = dt3.NewRow();

               dt3.Rows.Add(row1);


               Session["MyDataTable"] = dt3;

               GridView1.DataSource = dt3;

               GridView1.DataBind();

               cnn.Close();
           }
       }
   }

and here is my aspx code :

ASP.NET

<body>
    <form id="form1"  runat="server">
    <div>
    <asp:GridView ID="GridView1" runat="server" >
        <Columns>
            <asp:CommandField ShowEditButton="True" />
            <asp:CommandField ShowDeleteButton="True" />
            <asp:ButtonField CommandName="Cancel" HeaderText="Operation" ShowHeader="True" 
                Text="Insert" />
        </Columns>
    </asp:GridView>
    </div>
    </form>
    
</body>
