master page error message

Question

In a vb.net 2010 web form application, I have the start of code for a master page listed below:

#Region "Private Sub Page_Load(ByVal sender As System.Object, ByVal e As

System.EventArgs) Handles MyBase.Load"

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As

System.EventArgs) Handles MyBase.Load

_master = CType(Page.Master, MasterPage)

_master.PageTitle = "Attendance"

In the master page, there is an area to display error messages. When I have decided to place an

error message in the master page, I have made a call to a (static) shared function from an ajax call

to obtain data from the sql server database. The ajax call is made from a javascript function.

Thus can you tell me if there is away that I can access the error section of the of the master page?

Basically I need to have the master page with scope to access.

Thus can you tell me if this is possbile and/or show me the code on how to solve my problem?
