try

<asp:TextBox runat="server" ID ="txtCount" />
      <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
        <asp:GridView ID="GridView1" runat="server"></asp:GridView>

protected void Button1_Click(object sender, EventArgs e)
      {
          DataTable dt = new DataTable();
          int count = 0;
          int.TryParse(txtCount.Text.Trim(), out count);
          for (int i = 1; i <= count; i++)
              dt.Columns.Add(i.ToString());
          for (int i = 0; i < count; i++)
              dt.Rows.Add(dt.NewRow());

          GridView1.DataSource = dt;
          GridView1.DataBind();


      }
