Hi Chris,

I have done this once because some of our portal users requires low download size
of the portal's webpages due to limitation in their bandwidth.

/* Create this function */

public static string DisableThemes(string Url, bool Disable)
{
string RUrl = Url;
if(Disable == true)
{
string NoSkin = "?SkinSrc=" + System.Web.HttpUtility.UrlEncodeUnicode("[G]Skins/_default/No Skin");
string NoContainer = "&ContainerSrc=" + System.Web.HttpUtility.UrlEncodeUnicode("[G]Containers/_default/No Container");
RUrl = Url + NoSkin + NoContainer;
}
return RUrl ;
}

/* Call the DisableThemes function */

protected void Button_Click(object sender, EventArgs e)
{
string OriginalUrl = Globals.NavigateURL(PortalSettings.ActiveTab.TabID, "ViewDocument", "mid=" + ModuleId.ToString());
string NoThemesUrl = DisableThemes(OriginalUrl,true);
Response.Redirect( NoThemesUrl);
}


I don't know if there is a better way to do this, but hope this helps.
