Issues with regular expression control

emmablizzard · Apr 28, 2012

I have a page with the usual email / password text boxes, and a regular expression control to ensure the email address is of the form "[email protected]" but when I run the page, Internet explorer reports that it "cannot find script library webuivalidation.js", I can find no reference to this anywhere on msdn. Any ideas? Also on the page I have a "send my password" button - how can I ensure the default button (the one executed when the user hits enter is the "login" button, not the "send my password button"? TIAFor the time being I think you can fix this by adding: <%@ Page ClientTarget="Downlevel" %> to the top of your ASP.NET Web page, because this forces the controls to render to a downlevel browser (i.e., one that does not use client-side JavaScript validation). The file it is complaining about should be found in: C:Inetpubwwwrootaspnet_clientsystem_web1_0_3705_0 It should have been there upon installation of the .NET Framework. The file WebUIValidation.js contains the following JavaScript code: ########################### //<script> var Page_ValidationVer = "125"; var Page_IsValid = true; var Page_BlockSubmit = false; function ValidatorUpdateDisplay(val) { if (typeof(val.display) == "string") { if (val.display == "None") { return; } if (val.display == "Dynamic") { val.style.display = val.isvalid ?
