Hello,

When I open a Window with a skin applied, the backgroundcolor is different between IE and FF. Tested with IE7, 8 and FF3.

IE will open te window with white background and FF with black (see screenshots attached). Any idea's why?

Reproduce by:

- Start a new Telerik WebApplication through the template version 2009 Q3 SP1 .Net 3.5 (first 2009 Q3 release had same problem)
- Set Skin in dialog to Black

- Open default.aspx and paste below code:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml">  
        
            <head runat="server">  
        
                <title></title>  
        
                <telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" /> 
        
                <telerik:RadScriptBlock ID="rsblclient" runat="server">  
        
                    <script type="text/javascript">  
        
                        function openRequest() {  
        
                            var oWnd = $find("<%=RadWindow1.ClientID%>");  
        
                            oWnd.setUrl('Webform1.aspx');  
        
                            oWnd.show();  
        
                        }  
        
            </script> 
        
            </telerik:RadScriptBlock> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server">  
        
                    <Scripts> 
        
                        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" /> 
        
                        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" /> 
        
                    </Scripts> 
        
                </telerik:RadScriptManager> 
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                </telerik:RadAjaxManager> 
        
                <telerik:RadSkinManager ID="RadSkinManager1" Runat="server" Skin="Black">  
        
                </telerik:RadSkinManager> 
        
                <div> 
        
                    <asp:Button ID="btnOpen" runat="server" Text="Open window" OnClientClick="openRequest(); return false;" /> 
        
                    <telerik:RadWindow ID="RadWindow1" runat="server" Modal="true" NavigateUrl="WebForm1.aspx">  
        
                    </telerik:RadWindow> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

Hello Yeroon,

The parent element of the iframe rendered by RadWindow is a table cell with black (not black, actually, but #080808) background for that particular skin. On the other hand, in IE and FF the <iframe /> and document's background color is supported differently. The difference is that the background of a web-page that does not have any CSS background settings applied is transparent in FF, while in IE it is white, and what you see is actually the black background of the parent element of <iframe />. Unfortunately, the only fix to make things similar in both browsers is to set black (or any color you like) background to the <body /> or <html /> of the page that you load in RadWindow.

All the best,
