Hi Andy,

(For some reason the notification does not work for me so I apologize for not responding earlier )

This is a brilliant solution to a problem I am sure every skin developer deal with. Thank you for sharing this, I'll try it and hope to get it to work.

Thank you,

Yehuda

Thank you very much for this post.  I just have a question because I am still a novice at asp.net.

I was wondering how to make a codebehind file inherit the DotNetNuke.UI.Skins.Skin.  I know how to make the ascx use a different codebehind file.

If my skin is blue.ascx and my code behind file was css.cs then the top line would be as follows I would think.

<%@ Control language="c#" CodeBehind="css.cs" AutoEventWireup="false" Explicit="True" Inherits="css" %>

And this is my css.cs file

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

/// <summary>
/// This is used for conditional comments for CSS
/// </summary>
public partial class css : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string cssFixFile = null;
        // Note, "Firefox", "Opera", "Netscape" can all be detected using this method.    
        if (Request.Browser.Browser.Equals("IE"))   
        {      
            // IE detected      
            //      
            if (Request.Browser.MajorVersion == 7)      
            {         
                // IE7 detected - create a full path to the skin_IE7.css file         
                cssFixFile = Path.Combine(this.SkinPath, "skin_IE7.css");      
            }      
            else if (Request.Browser.MajorVersion == 6)      
            {         
                // IE6 detected - create a full path to the skin_IE6.css file         
                cssFixFile = Path.Combine(this.SkinPath, "skin_IE6.css");      
            }      
            else if (Request.Browser.MajorVersion == 5 && Request.Browser.MinorVersion == 5)      
            {         
                // IE5.5 Detected - create a full path to the skin_IE5_5.css file         
                cssFixFile = Path.Combine(this.SkinPath, "skin_IE5_5.css");      
            }      
            else if (Request.Browser.MajorVersion <= 5)      
            {         
                // IE5 or less detected - create a full path to the skin_IE5.css file         
                cssFixFile = Path.Combine(this.SkinPath, "skin_IE5.css");      
            }      
            // etc... more browser detection possible   
        }   
        // Load in the CSS file for the browser   
        if (cssFixFile != null)   
        {      
            // If a CSS file is needed, this part loads it in      
            HtmlGenericControl link = new HtmlGenericControl("LINK");      
            link.Attributes.Add("rel","stylesheet");      
            link.Attributes.Add("type","text/css");      
            link.Attributes.Add("href", cssFixFile );      
            Controls.Add(link);   
        }
    }
}

I am not sure I need all those namespaces, but I figured this would be the best place to ask.  Also I am not sure where to put the inheritance of DotNetNuke.UI.Skins.Skin in my css.cs file. 

I am sorry I am asking dumb questions.  Like I said, I am still a novice at asp.net and have written only a few web apps in C# using asp.net. 

Thanks and I am sorry to bug you.
