Hi
I have a master page from which i derive all the pages. On the master page i have a label called userLoginName (by default the text is blank.)

From the login page , on the click event of the login button i have this code:

VB

Dim _logName = Trim(LoginName.Text)
Dim _pwd = Trim(Password.Text)

If Me.ValidateUser(_logName, _pwd) = True Then

    'display users etails

    Dim mpLabel As Label
    mpLabel = CType(Master.FindControl("userLoginName "), Label)

    'change the userLoginName text to: your login is successfull + user Name
     mpLabel.Text = "your login is successfull" & _logName

    'Redirect user to the appropriate page
    If ViewState("_UserPrivilege") = "Administrator" Then
        Response.Redirect("~/Adminstrator/index.aspx")
    ElseIf ViewState("_UserPrivilege") = "Terminal User" Then
        Response.Redirect("~/TerminalUsers/index.aspx")
    End If

Else
    StatusLabel.Text = "Please your login Name or Password is incorrect."
    Exit Sub
End If

After Redirecting the page to the appropriate page, then i dont see the message + user login name.

There's all sorts of issues with this code. However, at the core, the way I always do this, is to create a base page class for all my pages. In that base class, I expose a property which is the Master property of the page, cast to the type of the MasterPage class I am using. Having done that, I can easily interact with my master page in my content pages. However, I would NEVER expose the textbox directly, I'd expose a property to get and set it's text.

i see, using the set and get method from a property created on the master page.
- you mean all the pages must access this property on their page load event?

but can you give a sample example of what your are talking about? both from the proprety of the master page and one content page.
Thank you.
