Form Validation

[TCORDON]

Is there a way to make the form validation highlight the fields where the
errors occur? (change the backcolor of the textboxes)?

And second, perform validation without postback and run some Javascript?

TIA

Hi,

Use a custom validator control. You can write your own routine in javascript for validation and in the process, highlight the fields that you want highlighted.

Keep in mind though, that if you're going to be highlighting server side controls, you'll need their ClientIds, and that you can get from server side code. So, you'll need to write your custom javascript in the server side and plugging in the clientid values as you generate it.

Instead of rewriting every validator with a custom validator, consider an
alternative. I wrote a replacement to the ASP.NET validators called
Professional Validation And More (http://www.peterblum.com/vam/home.aspx).
You can set the style sheet of fields that have errors. You can have it set
focus to the fields with the errors. There are several other techniques to
attract the user's attention on its 25 validation controls. My validators
provide client-side validation on many more browsers than the ASP.NET
Validators in ASP.NET 1.x.
