I have an MVC page that has many controls on it, including a Telerik MVC grid. Most of my editors are using DataAnnotations for validation (Required, Range, etc.). However, I'm trying to come up with a way to validate whether or not at least one item exists within the grid. Is there a way to do this? Nothing is jumping out at me in the documentation. Any help would be welcome!

Hi Chad,

This can be done by using a custom validation rule on a hidden input with an explicitly specified tooltip position. I prepared a proof of concept example that you can check here.

Thanks, Alex, I've seen this in the documentation (although your example is easier to understand). However, I already have a validation message box that uses the DataAnnotations of .NET. Does this validator also populate the standard validation message box? Or do I have to have two different display areas for validation?

Hi Chad,

Since this is a custom validation rule the Validator will automatically render the Tooltip, however you can override the position as shown in the example.
