Hello,

I'm developping a .NET 4 site. One of the pages includes a custom contact form that sends an e-mail message to the administrator.

Before sent the message, a method is executed to verify the form information (i.e.: regular expression for the sender e-mail address). If some data isn't correct, some controls in the form (OK or Not OK images) must be displayed for the required form field.

The form implements an ajax update panel (taking advantage of the sript manager) and, in the codebehind, an event handler asociated to the submit button, responsible to excutes the verification of data and message sending.

When the button is pressed, the explorer's status bar shows "Page with errors" message, and the Windows 2008 Event Viewer shows the following event code:
