Maybe check your namespaces and classes. Judging from the following
Source File: e:\inetpub\wwwroot\xyz\Employees_maint.aspx Line: 2
it looks like maybe this
VB Code:
<%@ Page language="vb" Codebehind="Employees_maint.aspx.vb" AutoEventWireup="false" Inherits="xyz.Employees_maint.Employees_maintPage" %>
should be
VB Code:
<%@ Page language="vb" Codebehind="Employees_maint.aspx.vb" AutoEventWireup="false" Inherits="xyz.Employees_maint" %>
Check and see if you actually have a code behind class located at xyz.Employees_maint.Employees_maintPage.
