Here is a way to dynamically load a skin based on the portal alias used to access the site. All you need is the following code pasted into a file by itself. Then you can name it something like "PortalAliasSwitcher.ascx" and put it in a skin folder along with the skins that you want it to load based on the Urls. Then go in and assign this file to the page, site, or host settings like you would normally do an individual skin. <%@ Control language="vb" AutoEventWireup="false" Explicit="True" %> <asp:placeholderid="SkinPlaceholder"runat="server"/> <scriptrunat="server"> Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ' Skincovered.com Portal Alias based skin switcher ' Switches the skin depending on the Url used to access the site ' Select this skin (PortalAliasSwitcher) as would any other skin in DotNetNuke ' The code below will load a skin from the same folder depending on the Url Dim skin As String = "" Select CType(HttpContext.Current.Items("PortalSettings"),PortalSettings).PortalAlias.HTTPAlias.ToLower() Case "hr.mydomain.com": skin = "HumanResources.ascx" Case "it.mydomain.com": skin = "InformationServices.ascx" Case Else: 'this skin will be loaded if no matches were made to the portal aliases above skin = "default.ascx" End Select 'this line loads the actual skin. SkinPlaceholder.Controls.Add(LoadControl(skin)) End Sub <script>

This is a great feature...Any Idea on how I could handle this with a wildcard? say .mydomain.com is skin A and .myotherdomain is skin B?

I'm sorry I missed this question earlier. For getting all the hosts on one domain you could just see if the domain name is in the Url. Something like: If Request.Url.Host.IndexOf("mydomain.com") > -1 Then skin = "mydomain.ascx" ElseIf Request.Url.Host.IndexOf("myotherdomain.com") > -1 Then skin = "myotherdomain.ascx" End If

It may be that you need to add a ControlPanel container to your skin. In the actual skin(s) that you are switching to, make sure that there is a line like this: <divid="ControlPanel"runat="server"></div> Also, if you want to link to a specific CSS file for the skin that you are switching to the easiest way is to put the css link directly in the skin like this: <linkrel="stylesheet"type="text/css"href='<%= Page.ResolveUrl("black_full.css") %>'/>

Another challenge for you John - I've tried to do something one way and then another but not able to get the exact results- I then thought a skin by role might be the answer... What I have is a site where tehre are three products being offered for sale (there might be more but you'll get the idea... ) I tried to add images with link based on role but I wanted to be upselling to these people, and not show the products if they have already bought it. EG.. I'm a registered user but bought nothing - so the idea is to show products 1, 2 & 3 But if I've bought product 1, I'd like to be able to upsell 2 & 3, but not show product 1 since they have bought it. If I've bought product 2, I'd like to upsell to product 3, but not show products 1 & 2, since they have bought them, and of course if they have bought product 3, dont' want to show any. I tried various methods of trying to hide one thing from another but coudn't work out the roles, so thought that the skin based on role would be ideal, as I'd just have these items displayed in the montage, but I then tried to jiggle the code around, and of course - was hugely... BAD at it.. So, is my thought going down the path? I thought the skin switcher features were so good, I could work with it. Thanks Nina

OH and I forgot to mention - that each of these skins has a role attached - as when you purchase the product you get assigned a role - I realise that is an important feature or otherwise how would you get it to work in the first place. Nina

Hi John, I am looking for options to apply a Low Graphics version on my site. From what I understand, it could be achieved by switching skin to NoSkin.ascx user control. But I would need to do that by clicking on my default page skin to switch to Low Graphics and switch back to the skin applied on the page by clicking on another link on the Low Graphics skin. Essentially its skin switching by link clicks rather than based on portal alias or role. Any advice would be great help. Regards Arif Shah

Hi Arif, You can switch skins using the querystring by passing it with the SkinSrc parameter. If you go into Site Settings or Page Settings and click on Preview button for a skin then you can see the format which is basically like this [G]/Skins/Skincovered_Feb/Login Which means use a host level skin [G] in the /Skins/Skincovered_Feb folder called Login.ascx If the Skin was at the portal level it would be [L] instead of [G] http://www.snapsis.com?tabid=1&SkinSrc=%5bL%5dSkins%2fSkincovered_Feb%2flogin
