I Have a radgrid using batch edit mode, with insert & edit item templates.

Grid is populated using OnNeedDataSource.

I also have RadAjaxManager.

There are RequiredFieldValidators in place to prevent fields being left empty. This shows an asterix next to each field that fails validation.

ValidationSettings have been configured to set ValidationGroup.

However, I am unable to get validation summary to display the 'ErrorMessage' to the user if a field is left empty and 'save' button clicked.

I am using Telerik® UI for ASP.NET AJAX, v4.0.30319.

Below is a very simple example to demonstrate the issue.

Is there some configuration I have missed either in the grid or in RadAjaxManager?

Thanks

Jason
