Is there a way to access validation error messages in the controller. I'm not finding them anywhere in ModelState.

Iterating over ModelState is used for this purpose. Something along these lines:
if (!ModelState.IsValid)
{
StringBuilder result = new StringBuilder();
foreach (var item in ModelState)
{
string key = item.Key;
var errors = item.Value.Errors;
foreach (var error in errors)
{
result.Append(key + " " + error.ErrorMessage);
}
}
TempData["Errors"] = result.ToString();
}

I realize this is old but I just stumbled into it looking for something else and will leave it here - perhaps someone could find it useful:
var err = ModelState.Values.SelectMany(x => x.Errors).Select(e => e.ErrorMessage);
foreach(var y in err)
{
// add each to your list of strings
}

You can validate an object in the controller using the Validator

I don't need to validate in the controller -- that's already being done by the MVC framework -- I just want to access the error messages generated by the framework's validation process in the controller rather than the view. I want to place the messages into the master view via TempData
