Yes, actually I created one simple page with validator and its working on all the browsers.

Then there is some setting in my application that is stopping to use validators on other browsers.

I am using Telerik Controls, have Tab control on my page, have different textbox, dropdown, grid inside each tab and separate buttons inside each tab to save those fields.

All of these works on IE perfectly but none of the validators get fired in any other browser.

Let me check my app configurations and what is extra on page.

Any suggestion what to check ?

I will definately update here once I find the reason.

Thanks again
