I'm fairly new to the skinning controls.
I have a logo image (a .gif) on my master page. I need the image url to change to a 'white on black' image as the page is initially loaded based on the cookie that is saved.
It works fine in the code below if I select a skin from the chooser and I notice that the chooser value is being updated form the cookie properly but I cannot for the life of me find a way to 'trap' either the cookie vale or the chooser value on the initial master page load.
Implementing the code below in the Master Page Load always seems to bring back an empty string.
If RadSkinManager1.GetSkinChooser.SelectedValue = "Black" Then
imgLogo.ImageUrl = "~/Styles/Images/RWLogoWhite.gif"
Else
imgLogo.ImageUrl = "~/Styles/Images/RWLogoBlack.gif"
End If
Can I get access to the cookie value as the page initiates?
I am fine with the built in skins and don't want to get involved with custom skins if possible ... please help.

Hello gonewalkabout,
Can you try getting the desired value from the RadSkinManager1.Skin property? Or try using the Text property of the RadSkinManager1.GetSkinChooser.

I have tried both of those solutions and neither return the required result.
On the Page Load of the master page the RadSkinManager1.Skin returns the value set in the control or an empty string when the value is removed.
The GetSkinChooser,Text returns an empty string regardless in the page.load event BUT show the last value set by the cookie properly once the page is rendered.
Can I not read the cookie 'value' somehow? I have PersistenceMode="Cookie" and I see what look like values in the values set in Persistence Mode and Persistence Key but I can't figure out the syntax fro reading them or is that possible?
If RadSkinManager1.Skin = "Black" Then
imgLogo.ImageUrl = "~/Styles/Images/RWLogoWhite.gif"
Else
imgLogo.ImageUrl = "~/Styles/Images/RWLogoBlack.gif"
End If
If RadSkinManager1.GetSkinChooser.Text = "Black" Then
imgLogo.ImageUrl = "~/Styles/Images/RWLogoWhite.gif"
Else
imgLogo.ImageUrl = "~/Styles/Images/RWLogoBlack.gif"
End If

Hello gonewalkabout,
Can you try opening a formal support ticket and send us a runnable sample illustrating your scenario for further debugging? Or you can share a sample code for replicating the problem here. We will check it out and turn back to you with our findings.

My code is below as requested.
I have two logos "~/Styles/Images/RWLogoWhite.gif" and "~/Styles/Images/RWLogoBlack.gif" (Image: "imgLogo"). Basically they are just negatives of each other, one suitable for the Telerik Black skin and the other for all other (basically white or close to white) Telerik skins. I have the RadSkinManager set to PersistenceMode="Cookie"
You will see, in bold, in my code behind, that I am attempting to trap for the skin value that has been saved in, I assume, a cookie and modify the imgLogo.ImageUrl accordingly on the page load of the master page.
Stepping through either of the methods does not return the value of the PersistenceMode="Cookie", yet once the page is rendered the skin chooser text value is correct.
Thanks for the help

Hi gonewalkabout,
Try moving the code for setting the logo image url on Page_PreRender as in the attached page.
Let me know if this works for you.

That got it!
Pretty dumb of me ... I know to try that solution but with the radskinshooser value showing up in the load event it never even occurred to me to try.
Thanks for the help.
