both gridview and database work row based, so 10 at once is an illusion.
so after 10 rows you need a loop to have them 1 by 1 in your db.
Are you using a List<> object or an ArrayList() object? You can bind that to the gridview.

Hi ,

I tried some code for you check this once,

This is just for sample to get you idea how to do it .in this example i just used session variable to store entered data .

ASP.NET

<form id="form1" runat="server">
  <table width="100%">
    <tr>
       <td>First Name</td>
       <td></td>
       <td>
           <asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown"></asp:textbox></td>
    </tr>
    <tr>
      <td>Last Name</td>
      <td></td>
      <td>    <asp:textbox id="TextBox2" runat="server" xmlns:asp="#unknown"></asp:textbox></td>
    </tr>
    <tr>
      <td colspan="3">
          <asp:button id="Button1" runat="server" text="Add" onclick="Button1_Click" xmlns:asp="#unknown" />
      </td>
    </tr>
  </table>
  <br />
<asp:gridview id="GridView1" runat="server" xmlns:asp="#unknown">
</asp:gridview>

</form>

after this you've to write some code

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("fname");
        dt.Columns.Add("lname");
        DataRow dr = dt.NewRow();
        dr[0] = "Murali";
        dr[1] = "krishna";
        dt.Rows.Add(dr);

        Session["TempData"] = dt;
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}
protected void Button1_Click(object sender, EventArgs e)
{
    DataTable dt = (DataTable)Session["TempData"];

    DataRow dr = dt.NewRow();
    dr[0] = TextBox1.Text;
    dr[1] = TextBox2 .Text ;
    dt.Rows.Add(dr);
    Session["TempData"] = dt;
    GridView1.DataSource = (DataTable)Session["TempData"];
    GridView1.DataBind();
}

Here i'm just made this code for testing you've to modify this to fullfill your requiremens

All the Best
