突出显示某个单元格内容
要求：如果某个员工的起薪大于20000，就用红色的背景颜色突出显示：
前台代码：
View Code
1 <asp:GridView ID="GridView1" ShowFooter="true" runat="server" AutoGenerateColumns ="false"
2 style="border:solid 1px black" onrowdatabound="GridView1_RowDataBound">
3 <Columns>
4 <asp:BoundField DataField="编号" HeaderText ="编号" />
5 <asp:BoundField DataField ="姓名" HeaderText ="姓名" />
6 <asp:BoundField DataField ="邮政编码" HeaderText ="邮政编码" />
7 <asp:BoundField DataField ="家庭住址" HeaderText ="家庭住址" />
8 <asp:TemplateField HeaderText ="出生年月">

10 <%#Eval("出生年月","{0:yyyy-MM-dd}")%>
11 </ItemTemplate>
12 </asp:TemplateField>
13 <asp:BoundField DataField ="起薪" HeaderText ="起薪" />
14 </Columns>
15 <HeaderStyle Font-Bold="true" BackColor="#006699" ForeColor="White" />
