I'm trying to override the On_Updating event of one of my Dynamic Data fields and throw an exception under certain circumstances. For example:
Partial Public Class Section4
Private Sub OnContact_EmailChanging(ByVal value As String)
If Not [Char].IsUpper(value(0)) Then
Throw New ValidationException( _
"Email must start with an uppercase letter.")
While this works to catch the scenario, it just throws an unhandled exception, so I get an error page.
But according to the MSDN documentation,
"Any validation exceptions that are thrown in the data model are caught by the DynamicValidator control.
If a page contains a DynamicValidator control, the error can be displayed in the page."
So this is in my Edit.aspx, which has a DynamicValidator control. Are they wrong?

I think that this has been seen before and there was a fix for this as the error was being wrapped in some other exception see the ImprovedDynamicValidator.cs in the Dynamic Data Futures project here

Shucks, I guess they haven't put this in DD4, as I'm using .NET 4 for this project.

You may be able to use this in DD v4 if you look how they wired it up in the old Futures project.

Not gonna lie, I don't think I'd know where to start. I haven't found the plain-jane DynamicValidator hiding within the DynamicData folder, so I'm assuming it's a control in a library somewhere, but beyond that...

This article may be a good place to start.
Not quite the same reason, but it also requires the DynamicValidator to be enhanced so it might help.

The DynamicDataValidator is in the old Futures project inside the Controls folder.

Will the DynamicValidator be fixed in the next DD release so we don't have to keep using the ImprovedDynamicValidator?

Good Question [:D] and did that get you the ImprovedDynamicValidator?
