I have a custom paging control that I am using in my application.
The markup for the control is listed below. The problem I am having is that the slider doesn't always render the skin correctly. When it renders the only thing I see is a link with the word "Drag"; please see the attached image. I tried adding the reference to the top of the page to Get the WebResource for the skin but that didn't work. Any help would be greatly appreciated.

<asp:Panel ID="pagerContainer" CssClass="pagercontainer" runat="server">
 
    <table border="0" width="100%" cellpadding="2" cellspacing="2">
        <tr>
            <td valign="middle" width="105px" nowrap="nowrap">
                <asp:Panel ID="LeftContainer" runat="server" CssClass="pagerCommand">
                    <asp:ImageButton AlternateText="First Page" CommandName="First" ID="firstPageButton"
                        ImageAlign="AbsMiddle" ImageUrl="~/Images/first.gif" runat="server" ToolTip="First Page" />
                    <asp:ImageButton AlternateText="Previous Page" CommandName="Previous" ID="previousPageButton"
                        ImageAlign="AbsMiddle" ImageUrl="~/Images/prev.gif" runat="server" ToolTip="Previous Page" />
                </asp:Panel>
            </td>
            <td valign="middle" width="175px">
                <asp:Panel ID="sliderPanel" CssClass="pagerCommand" runat="server">
                <telerik:RadSlider ID="slider" runat="server" AnimationDuration="0" 
                        Orientation="Horizontal" EnableViewState="true"
                    SmallChange="1" ShowDecreaseHandle="false" ShowIncreaseHandle="false" Width="175px"
                    Skin="Web20" AutoPostBack="true"
                    EnableEmbeddedSkins="true">
                </telerik:RadSlider>
                </asp:Panel>
            </td>
            <td valign="middle" width="105px">
                <asp:Panel ID="rightContainer" runat="server" CssClass="pagerCommand">
                    <asp:ImageButton AlternateText="Next Page" CommandName="Next" ID="nextPageButton"
                        ImageAlign="AbsMiddle" ImageUrl="~/Images/next.gif" runat="server" ToolTip="Next Page" />
                    <asp:ImageButton AlternateText="Last Page" CommandName="Last" ID="lastPageButton"
                        ImageAlign="AbsMiddle" ImageUrl="~/Images/last.gif" runat="server" ToolTip="Last Page" />
                </asp:Panel>
            </td>
            <td align="right">
                <asp:Label ID="positionLabel" runat="server" CssClass="pagerinfo" />
            </td>
        </tr>
    </table>
 
<asp:HiddenField ID="SliderHiddenField" runat="server" />
 
</asp:Panel>

Hello Chad,

As I could see from your screehsnots some of the Slider resources are not loaded on the page. I could not tell what is happening with your application, but I have tested your code with a very few changes (I have added some absolute img urls):

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <asp:Panel ID="pagerContainer" CssClass="pagercontainer" runat="server">
        <table border="0" width="100%" cellpadding="2" cellspacing="2">
            <tr>
                <td valign="middle" width="105px" nowrap="nowrap">
                    <asp:Panel ID="LeftContainer" runat="server" CssClass="pagerCommand">
                        <asp:ImageButton AlternateText="First Page" CommandName="First" ID="firstPageButton"
                            ImageAlign="AbsMiddle" ImageUrl="http://cdn1.iconfinder.com/data/icons/Primo_Icons/PNG/48x48/button_black_rew.png"
                            runat="server" ToolTip="First Page" />
                        <asp:ImageButton AlternateText="Previous Page" CommandName="Previous" ID="previousPageButton"
                            ImageAlign="AbsMiddle" ImageUrl="http://cdn1.iconfinder.com/data/icons/Primo_Icons/PNG/48x48/button_black_rew.png"
                            runat="server" ToolTip="Previous Page" />
                    </asp:Panel>
                </td>
                <td valign="middle" width="175px">
                    <asp:Panel ID="sliderPanel" CssClass="pagerCommand" runat="server">
                        <telerik:RadSlider ID="slider" runat="server" EnableViewState="true" ShowIncreaseHandle="false"
                            Width="175px" Skin="Black" AutoPostBack="true">
                        </telerik:RadSlider>
                    </asp:Panel>
                </td>
                <td valign="middle" width="105px">
                    <asp:Panel ID="rightContainer" runat="server" CssClass="pagerCommand">
                        <asp:ImageButton AlternateText="Next Page" CommandName="Next" ID="nextPageButton"
                            ImageAlign="AbsMiddle" ImageUrl="http://cdn1.iconfinder.com/data/icons/Primo_Icons/PNG/48x48/button_black_rew.png"
                            runat="server" ToolTip="Next Page" />
                        <asp:ImageButton AlternateText="Last Page" CommandName="Last" ID="lastPageButton"
                            ImageAlign="AbsMiddle" ImageUrl="http://cdn1.iconfinder.com/data/icons/Primo_Icons/PNG/48x48/button_black_rew.png"
                            runat="server" ToolTip="Last Page" />
                    </asp:Panel>
                </td>
                <td align="right">
                    <asp:Label ID="positionLabel" runat="server" CssClass="pagerinfo" />
                </td>
            </tr>
        </table>
        <asp:HiddenField ID="SliderHiddenField" runat="server" />
    </asp:Panel>
    </form>
</body>
</html>

Attached is sliderPlayer.gif showing the result in the browser. I could only guess if this is similar to the result that you expect. If it`s close and it works on my side but does not work on yours, we will need us to send us a simple sample project with your application and the issue reproduced, so we would be able to investigate it further.

As I could see only a picture od the problem, this is also a guess, but it could be the known IE CSS limitation problem, and that`s why some of the CSS resources were not loaded on the page.

There is a blog post on our website: Internet Explorer CSS Limits where the problem is described in detail and suggests several ways to fix the issue.

But in shortly, I will suggest you to add RadStyleSheetManager to your application. RadStyleSheetManager control gives developers the advantage of a simple drag-and-drop to achieve the combination of resources to a single request. All you need is to add a RadStyleSheetManager to your page and the stylesheet requests will be combined into a single request:

<telerik:RadStyleSheetManager ID="RadStyleShM1" runat="server"></telerik:RadStyleSheetManager>

All the best,

Thanks for the help.You were correct in your assumption of the issue. The issue was related to the 31 stylesheet limitation; which at the time I was unaware of until this issue arose. I  appreciate the quick reply and help with this issue.
