Apply Theme with VB codefile.

4/14/2008 8:00:57 AM

0/0

I'm trying to add a theme to my masterpage (so its applied to all my content pages) programmatically. So far i have my master page with this:

<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>

...And my "MasterPage.master.vb" code looks like this:

1    Partial Class MasterPage
2        Inherits System.Web.UI.MasterPage
3    
4        Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
5            Page.Theme = CType(Session("default_theme"), String)
6        End Sub
7    End Class

I run one of my content pages (which are build from my masterpage) and it comes up with this "Exception Details: System.InvalidOperationException: The 'Theme' property can only be set in or before the 'Page_PreInit' event."

This may sound like a dumb question but why is this not working?

Although you named your method Page_PreInit, you have set it up to handle the Load event. Load occurs after PreInit.

You need to set the Theme property in the Pages PreInit event.

Hi Friend
User profile to do this
Kindly review the code?

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Profile.UserName = TextBox1.Text
        Profile.MyThemes = DropDownList1.SelectedValue
        Response.Redirect("ProfileTheme.aspx")
    End Sub

With Friendly,

Thanks Mbanavige for that. The debugging did say something about "You need to set the Theme property in the Pages PreInit event.

So i would change this:

1    Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

to this ?:

1    Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As EventArgs) Handles Me.PreInit
 But then i get errors BC30590: Event 'PreInit' cannot be found ?

The master page doesn't have a PreInit event, so you have to do this either in each page, or elsewhere. I use global.asax to hook up events so that setting the theme happens for all pages. See http://blogs.ipona.com/davids/archive/2008/03/30/8482.aspx for more details.
