GridView is not rendered until you set its dataSource property and call dataBind().

Try following

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            int[] i = new int[10];
            GridView1.DataSource = i;
            GridView1.DataBind();
        }

    }

You may change the Length of the Array to get more rows.

int[] i = new int[100];

Change the Control name in your GridView

<ItemTemplate>
        <asp:TextBox Id="dregreName"     runat="server"></asp:TextBox>
   </ItemTemplate>

Solution 2

you can not see this grid if you did not provide datasource to the grid because grid is used to show some bound data
i used following line at page load to show 3 lines in grid

GridView1.DataSource = new string[] { "", "", "" };

Hope u could use this.
