Server.GetLastError is Nothing on custom error page

I'm trying to write a custom error page, to display the error message within a page matching the "house style". I thought that I could use Server.GetLastError to get the exception that was thrown, but it has a value of "Nothing".

In my web.config I have:

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

And in the code-behind of error.aspx I have:

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim ex As Exception = Server.GetLastError   ' <--- ex is Nothing at this point
        lblError.Text = ex.Message

    End Sub

This is making my custom error page pretty useless. What am I doing wrong?

The defaultRedirect occurs AFTER the server has processed all the error junk, if you want to get the last error, you either have to do it in Page_Error or Application_Error

Maybe i am missing something but i have the following code in the pack of my page, but the sub Page_error never gets called when the error page gets loaded. What am i missing?

        Dim PageException As String = Server.GetLastError().ToString()

        Dim strBuild As New StringBuilder()

        strBuild.Append("Exception!")

        strBuild.Append(PageException)
