When we were working with ASP.NET MVC 2, we needed to write our own JavaScript to get Client-Side Validation Summary with jQuery Validation plugin. I am one of those unfortunate people still stuck with .NET Framework Runtime 2.0 and .NET Framework 3.5; meaning I am still on ASP.NET MVC 2. So I will still keep on supporting by answering any question you may have with my original code. Long awaited ASP.NET MVC 3 has been released, and it supports Client Side Validation Summary with jQuery out-of-the-box ......
The ASP.NET MVC integration with the jQuery Validation Plugin does not work the way how I want it to with the Validation Summary Errors.
I want to display the actual errors messages in the Validation Summary "control" and asterisks next to the User Input Fields (textboxes and dropdowns). This is a blog post on how to tweak the MicrosoftMVCJQueryValidation.js file to achieve the desired behavior.
