To call a javascript function prior to postback, take the button out of the form. Use the button to call javascript, and if everything is ok, use the javascript to call form.submit(). Rob http://tagyurit.com

use onclick = "return yourfunction()" Now from the function
return falsewhen you show the alert, the page will then not be posted back. :)function yourfunction()
{
if ...
{
alert('invalid');
return false;
}
return true;
