Howdy StrataFramers:



I'm trying to handle the ErrorSaving event of a business object that is used on an .ASPX page and that is referenced in the ApplicationBasePage as such.



Public WithEvents oPrefix As Prefix



On the page where the saving is taking place I put the following code as per the help topic ErrorSaving:



Private Sub ErrorSaving(ByVal e As MicroFour.StrataFrame.Business.ErrorSavingEventArgs) Handles oPrefix.ErrorSaving



Dim lcErrorText As String = ""

lcErrorText = Me.GenerateWarningTable(e.ToString)

SetErrorsLabelState("Show", lcErrorText)



End Sub



But I get an error saying the signatures do not match. It looks like the ErrorSaving example caters to WinForms so I guess my question is how do I snag this event in an ASPX page so I can capture the Unique Key Violation message from the database and display it to the user. I tried the same thing in the web example from Micro4 and the same error occurs. I guess I'm doing the same thing incorrectly in both places.



Thanks guys,

When code starts executing twice, this is generally a sure fire indication that you have more than one handler.  Since an event can be managed by multiple handlers, if the handler is not removed (or one gets added that is not expected) then you have code re-execution.  This doesn't sounds like a BO issue...it is more than likely coming from a handler you have added someplace...and keep in mind you are working on the web, so if the form is posted and you did not remove the previous handler, you could then have multiple handlers.  Be sure to keep the IsPostBack property in mind on the web when manually creating or adding handlers.
