I have defined in my web.config a default error page:

<customErrors mode="On" defaultRedirect="Erro_Padrao.aspx">
</customErrors>

Now, I’m forcing an error in one of my pages to test the error page:

Try
    Dim var1 As Integer = 1
    Dim var2 As Integer = 0
    Dim result As Integer = var1 / var2

Catch ex As Exception
    Throw ex
End Try

The error occurs but nothing happens.

Anyone?

Thank you.

Edit:

I am trying this inside a method that is called by a DevExpress’ ASPxGridView component. The exception message is not shown in the default .NET yellow error page, but this grid somehow handles the exception and “blocks” the redirection(yeah, the error message is in portuguese):

enter image description here

If I try to do this in the page_load event, for example, the redirection for the default error page works fine.

    Found an article on DevExpress’ ASPxGridView pointing out, that any unhandled exception within an GridView will be catched automatically and the CustomErrorEvent will be raised. See only documentation of DevExpress.

    The CustomErrorText event occurs when any exception is raised within
    the ASPxGridView, and allows you to change the error text displayed by
    default. This can be useful, if you want to localize error messages.
