Multiline TextBox Length Validation

Posted by: adnanrashid on: January 10, 2009

Unlike the normal TextBox, the MaxLength property doesnt work for MultiLine TextBox. Heres a small trick to solve the problem:

<asp:TextBox ID=”txtExample” runat=”server” TextMode=”MultiLine” />
<asp:RegularExpressionValidator ID=”revExample” runat=”server”

Heres a quick tip. If you need to include a request for read receipt like Microsoft Outlook while sending mails through Asp.net, just add the Disposition-Notification-To Header to the MailMessage.

MailMessage mm = new MailMessage(fromAddress, toAddress);
mm.Subject = subject;
mm.Headers.Add(“Disposition-Notification-To”, [...]

http://www.yourapplication.com?customer_id=15
Now if somebody replaced 15 with say 10 or any other number, they can pull up other customer information. And thats a bad [...]
