I just added the code to change the theme and use the cookie but now for some reason the drop down doesnt seem to do anything.


Here is the code in .Master.vb:

Protected Sub ThemeList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ThemeList.SelectedIndexChanged
Dim preferredTheme As HttpCookie = New HttpCookie("PreferredTheme")
preferredTheme.Expires = DateTime.Now.AddMonths(3)
preferredTheme.Value = ThemeList.SelectedValue
Response.Cookies.Add(preferredTheme)
Response.Redirect(Request.Url.ToString())
End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim selectedTheme As String = Page.Theme
Dim preferredTheme As HttpCookie = Request.Cookies.Get("PreferredTheme")
If preferredTheme IsNot Nothing Then
selectedTheme = preferredTheme.Value
End If
If Not String.IsNullOrEmpty(selectedTheme) AndAlso ThemeList.Items.FindByValue(selectedTheme) IsNot Nothing Then
ThemeList.Items.FindByValue(selectedTheme).Selecte d = True
End If
End If


Here is the code in the BasePage class:

Private Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit
Dim preferredTheme As HttpCookie = Request.Cookies.Get("PreferredTheme")
If preferredTheme IsNot Nothing Then
Page.Theme = preferredTheme.Value
End If
End Sub

Hi Alex,

Did you enable AutoPostBack for the drop down list in the markup section of the page?
