I am working on a project that use MVC 2.0 with Kendo UI. We decided to use AJAX validation instead of MVC Model level validation; which means validation happens during most "onchange" events on HTML controls. We coded the red CSS "highlight" on HTML controls when error happens and remove the highlight when there is no error. If there are multiple controls (e.g. checkboxes) we will highlight all of them when error occurs...and of course, error messages related to multiple fields validaton....
We get it sort of working but we had to implement a lot of javascript/jQuery coding on each web form page (including control id/name matching on the validation message) and does not seem to be able to implement it as a common routine against all web forms. We are also wondering if there is some sort of validation library already out there that more or less achieving the same thing...
Any suggestions?
