What Alternatives are there to AJAX Control Toolkits ValidationCallOutExtender

I am having issues with the Calloutextender in Chrome. If an error occurs on an element on the page which is not in view, The callout extender posi开发者_运维问答tions itself at the top of the viewport. That is it does not set focus on the element and move the browser caret and view to focus on the element in error. When working, this would usually see focus set on the element in error and the callout displayed correctly.

Do telerik do one? I know there is a JQuery alternative, but is it any good (can I target just target specific elements)

Thanks.

I have collated information I have found from a number of different sources to help as quickly as possible.....

So, if the the AJAX control toolkit is failing you, consider upgrading to the April 2010 release. Be aware that upgrading, though, can be a bit painful.

Right then, I am using Telerik controls in a .NET 3.5 environment and this has meant I have had to go with the following solution here (and it works!!):

However, if you have different set up (.NET 4, non-Telerik solution) check out this link
