Question

I have a Base MasterPage class, from which my masterpages will inherit. I have some javascript functions there for it s child pages to include. As it s a base class, it does not have a visual designer nor I can add XHTML code. I need to add a hidden field to the class so I can set it s value in the javascript code, and when a postback occurs I can get the setted value on my content pages. Yet I fail to achieve this, for when I try to add the hidden field to the base masterpage s control collection I get a render error (Content Encoding error if viewed in Firefox). And If I try cheating and registering a hidden field via scriptmanager with the same name in stead of adding the control to the control collection, well... I get the value as empty. How could achieve this?

Answer 1

Public Class MyBaseMaster
    Inherits MasterPage

    Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
      If Not Page.IsPostBack Then
         Page.ClientScript.RegisterHiddenField("MyHiddenField1", "initialvalue")
      End If
    End Sub
End Class

您可以通过<代码>Request.Form (“MyHidden Field1”)(因为它不是服务器控制,而是网页控制的一部分)。
