" HtmlMeta pagedesc = new HtmlMeta();",
" pagedesc.Name = \"Description\";",
" pagedesc.Content ="+TextBox2.Text+";",
" this.page.Header.Controls.Add(pagedesc);",
" HtmlMeta pagekeywords = new HtmlMeta();",
" pagekeywords.Name = \"keywords\";",
" pagekeywords.Content = "+TextBox3.Text+";",

" output.Text = \""+txtpagename0.Text.ToString()+"\";",
" }",
