Child controls on the page level

Accessing LoginView’s templated child controls on the page level

I blogged last week about my difficulty to access child controls inside the asp:LoginView server control. Fortunately, I bumped into an article just in time to get the answers I need. So here’s the complete solution to the problem:

Imports System
Imports System.Data
Imports System.Configuration
Imports System.Web
Imports System.Web.Security
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Web.UI.WebControls.WebParts
Imports System.Web.UI.HtmlControls

Namespace Fix

Public Class LoginViewFix
Inherits LoginView

<TemplateInstance(TemplateInstance.Single)> _
Public Overrides Property AnonymousTemplate() As System.Web.UI.ITemplate
  Get
     Return MyBase.AnonymousTemplate
  End Get
  Set(ByVal value As System.Web.UI.ITemplate)
     MyBase.AnonymousTemplate = value
 End Set
End Property

<TemplateInstance(TemplateInstance.Single)> _
Public Overrides Property LoggedInTemplate() As System.Web.UI.ITemplate
  Get
    Return MyBase.LoggedInTemplate
  End Get
  Set(ByVal value As System.Web.UI.ITemplate)
    MyBase.LoggedInTemplate = value
  End Set
End Property

End Class

End Namespace

So theres the code, but how do we use it? First, If you are using visual web developer, you have to click the add new item and choose Class, then rename it to Fix.vb, and the IDE will ask you to place the code to the App_Code Folder, just click yes, then cut and paste this code, and the runtime will automatically compile your code as part of the application. If you will use it on a specific page you have to add a Register directive like this: <%@ Register NameSpace=”Fix” TagPrefix=”fix” %>  after the @Page line, then in your code, since we override the <asp:LoginView />, you should now declare it as <fix:LoginViewFix />

Common try it, It worked perfoectly for me.
