Hi there -
I have a RADGrid in which I use GridTemplateColumns. In one of these templates I have an EditItemTemplate that contains a RadComboBox, and RequiredFieldValidator and and ValidatorCalloutExetension. The validator and callout work as expected when the grid is in edit mode until I add a RadAjaxManager to the page.
With the RadAjaxManager the validator by itself works correctly, however, when I add the ValidatorCalloutExtension back in I start receiving a JavaScript error: Sys.ArgumentUndefinedException: Value cannot be undefined. Parameter name: id
The problem seems to lie with the ValidatorCalloutExtension and the RadAjaxManager - is this anyone else is aware of, is there a "trick" I've missed anywhere?
I will try and put together a simplified code example to add to the post.
Many thanks,
Simon
