<asp:DropDownList ID="ddlOptions" runat="server" AutoPostBack="true"
onselectedindexchanged="ddlOptions_SelectedIndexChanged">
    <asp:ListItem Value="1">1asp:ListItem>
    <asp:ListItem Value="2">2asp:ListItem>
    <asp:ListItem Value="3">3asp:ListItem>
    <asp:ListItem Value="4">4asp:ListItem>
    <asp:ListItem Value="5">5asp:ListItem>
    <asp:ListItem Value="6">6asp:ListItem>
asp:DropDownList>

<asp:PlaceHolder runat="server" ID="ctrlPlaceholder">asp:PlaceHolder>
Code-behind
protected void ddlOptions_SelectedIndexChanged(object sender, EventArgs e)
{
   for (int cnt= 1; cnt<= Convert.ToInt32(ddlOptions.SelectedValue.Trim()); cnt++)
   {
       TextBox tb = new TextBox();
       tb.ID = "tb" + cnt;
       ctrlPlaceholder.Controls.Add(tb);
    }
}
