hi Petar Ivanov,

     Thanks for your quick reply ,i was using ultrawebmenu v6.2. here the snippet of my code

        If Menu1.Items(0) Is Nothing Then

            Dim newItem As New Item

            Dim newItem1 As New Item

            Dim newItem2 As New Item

            Dim newItem3 As New Item

            Dim newItem4 As New Item

            Dim newItem5 As New Item

            Dim newItem6 As New Item

            Dim newItem7 As New Item

            Dim newItem8 As New Item

            Dim newItem9 As New Item

            If Session("Status") = "Safety" Then

                newItem = Me.Menu1.Items.Add("Occurrence Entry")

                newItem.TargetUrl = "Instance_entry.aspx"

                newItem1 = Me.Menu1.Items.Add("Safety Home")

                newItem1.TargetUrl = "Safety_dept.aspx"

                newItem2 = Me.Menu1.Items.Add("Closure")

                newItem2.TargetUrl = "Action_plan_closure.aspx"

                newItem3 = Me.Menu1.Items.Add("Master Entry")

                newItem3.TargetUrl = "Master.aspx"

                newItem4 = Me.Menu1.Items.Add("User Rights")

                newItem4.TargetUrl = "UserRigts.aspx"

                newItem5 = Me.Menu1.Items.Add("Logout")

                newItem5.TargetUrl = "../login/loginpage.aspx"

end if 

and here the click event 

Protected Sub Menu1_MenuItemClicked(ByVal sender As Object, ByVal e As Infragistics.WebUI.UltraWebNavigator.WebMenuItemEventArgs) Handles Menu1.MenuItemClicked

        If e.Item.Text = "Logout" Then

                Session.Clear()

       End If

    End Sub
