Category: UI for ASP.NET AJAX
Type: Feature Request
Telerik Client-side Validation
Instead of utilising 3rd party jQuery or the boring old ASP client-side form/field validation why don't you guys develop your own that has nice look and functionality similar to this:


and you could also include a password strength indicator like this while your at it:


Not hard and it would nicely complement your current suite of tools, especially if it was styled from skins.

Hi folks,

Is this feature request still valid at the end 2020?

What functionality, appearance and features you will get more compared to the built-in ASP.NET Web Forms validators?

Have you tried the Kendo Validators? Do you find them suitable for your web forms projects? 

Would you expect server-side validation too or you are looking for client-side validators only?


Best Regards,
Progress Telerik

I agree that validation of radcontrols should be improved so when a radtextbox does not meet the requirement it auto styles to invalid and when it is valid it styles auto to OK. Have a look at the booking.com form fields. They nicely check when OK or get red or obvious highlighted when not OK. There is no easy way to get this done as far as I know and building huge javascripts to obtain this would be a pain. Would be nice to have a property like "invalidImageUrl"  and "validImageUrl" and "ShowValidationStatus" = yes/no and "ValidationStatusPosition"=left/right/top/bottom

I like the idea of a built in set of validation especially if it is outside of the page flow like the sample.  With validation reporting being inline all to often it screws up the look of a form.  Mine currently just use floating alert images but they have to be positioned differently for each control and are a pain.  So yes do a built in validation.  Just remember to cope with more complex rules, if this field is ticked then these are needing to be filled in type of thing.
