Trying to figure out where to catch validation exception.
I have a asp.net web form that has a formView control that is connected to a LinqDataSource control. Created a partial class to do the validation (see below). When the exception is thrown I cannot figure out where to catch it.
I expected to find and event on the LingDataSource control. I am new to using databound controls/data source controls so I am hoping this is a very easy.
Partial Public Class User
Private Sub OnUser_NameChanging(value As String)
If value.Contains("jon") Then
Throw New Exception("jon is not valid")
