is it possible to customize the error messages returned by an ajax response? In c# there are the Exception classes that have a variety of Messages - i.e. InnerMessage, Stack, etc. How can this be done on the client (i.e. via the AJAXResponseError handler)?
The CustomAJAXResponse available off of the Grid has a Message and Tag property that can both be set. In addition, you can add any number of string/object pairs to the AdditionalProperties property. You should get the ajax response error to fire so long as the action was in a container grid. There was a bug recently fixed (84361) where it didn't fire for WHDG actions. This should be resolved in an upcoming service release.
