我在母板页里写了下面这段style：
<style type="text/css">
.ListHead2
{
background-color: #E0E3E8;
height: 20px;
color: #000000;
font-family: Tahoma, Arial, Verdana, Tahoma, Arial;
font-size: 8.5pt;
font-weight: normal;
text-align: left;
cursor: default;
font-weight: normal;
background-image:url(../images/img_mnusep.gif);
background-repeat: no-repeat;
padding-left: 8px;
padding-right: 2px;
border : 0px;
border-bottom : solid 1px #A0A0A4;
}
</style>
然后我在内容页里有这样一个gridview：
<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="False" HeaderStyle-CssClass="ListHead2"
CssClass="List" BorderWidth="0px" DataKeyNames="criterionId" Width="100%">
<Columns>
<asp:TemplateField>
