Advanced ASP.NET Development: jQuery Validation and ASP.NET UpdatePanel

“Either we’re talking about a server, a system service, a desktop or web application, developed in C/C++, C#, ASP.NET, PHP…etc, data validation is a must: we just can’t deliver any real applications to the end-users, without having at least a basic level of data validation. What to do then? Should we just give up using UpdatePanel or the jQuery validation plug-in? The jQuery validation knows to prevent a regular FORM submit the server, but since the UpdatePanel performs an async. Add the regular jQuery validation routine: the submitHandler is triggered when the validation is successful, and it must set “True” for the formIsValid hidden field: to continue performing the Ajax async post-back. As we seen so far, jQuery is a great library to be used for client side scripting, and the jQuery validation plug-in is really useful, when it comes to get UI validation done quick, safe and fun.”
