我在.aspx页面中放置了
<iewc:TabStrip ID="tsMenu" runat="server"  TabDefaultStyle="PADDING-RIGHT: 3px; PADDING-LEFT: 3px; FONT-WEIGHT: bold; FONT-SIZE: 0.83em; PADDING-BOTTOM: 3px; MARGIN: 0px; COLOR: #8e3769; PADDING-TOP: 1px; FONT-FAMILY: Arial; BACKGROUND-COLOR: #f2e3ec; TEXT-ALIGN: center;center;border-color:#000000;border-width:1px;border-style:Solid;text-decoration:underline;"
      TabSelectedStyle="background-color:#993366;color:#ffffff" AutoPostBack="True" TabHoverStyle="PADDING-RIGHT: 3px; PADDING-LEFT: 3px; FONT-WEIGHT: bold; FONT-SIZE: 0.83em; PADDING-BOTTOM: 3px; MARGIN: 0px; COLOR: #8e3769; PADDING-TOP: 1px; FONT-FAMILY: Arial; BACKGROUND-COLOR: #f2e3ec; TEXT-ALIGN: center;text-decoration:underline;" Font-Size="10pt" OnSelectedIndexChange="tsMenu_SelectedIndexChange">
                <iewc:Tab Text="News"></iewc:Tab>
                <iewc:TabSeparator />
                <iewc:Tab Text="Pictures"></iewc:Tab>
                <iewc:TabSeparator />
                <iewc:Tab Text="Movies"></iewc:Tab>
            </iewc:TabStrip>
这段代码，但是这些标签不能用，还请大家给与指点。谢谢！
