But what it I use excludePropertyErrors=true in ValidationSummery? –nir Jun 18 '11 at 21:22 If you don't pass in a key to this function it will work. The key in this case would be the property name of your model. So if you do ModelState.AddModelError(string.Empty, "Error Message") and excludePropertyErrors = true it will still show up. –John Kalberer Jun 20 '11 at 15:30 Cool, Thanks!!! –nir Jun 20 '11 at 16:00 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Googl
