    Hi,
       I have a requirement to show/hide a button. But when I tried to hide the button from C# code behind page. Still a small rectangle is displayed on the screen. below is the code for that.

     btn_Cancel.Attributes["style"]="visibility:hidden;display:none";

    But it still displays small rectangular box. This is happening when I include FormDecorator in my page. When I looked at the style of that rectangular box using ie developer tool I see a style rfdSkinnedButton. how can I achieve this. I have to use Form decorator in my master page.
    Please help me on this ASAP.

    Thanks in advance.

    Hi Pradeep,

    You should  use CssClass to hide the button, and RadFormDecorator will not decorate it, e.g.
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <head id="Head1" runat="server">
        <title></title>
      
        <style type="text/css">
            .hiddenClass
            {
                display: none;
                }
        </style>
    </head>
    <body>
        <form id="form1" runat="server">
       <asp:ScriptManager ID="ScriptManager1" runat="server">
            <Scripts>
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            </Scripts>
        </asp:ScriptManager>
        <telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" />
        someText<asp:Button ID="btn_Cancel" Text="btn_Cancel" runat="server" CssClass="hiddenClass" />someText
          
        </form>
    </body>
    </html>
