SelectCommandType="Text" SelectCommand="select * from student">asp:SqlDataSource>
<asp:GridView ID="gv" runat="server" DataSourceID="ds" AutoGenerateColumns="false">

<asp:BoundField HeaderText="语文" DataField="chinese" />
<asp:BoundField HeaderText="数学" DataField="mathematics" />
<asp:BoundField HeaderText="英语" DataField="english" />
Columns>
asp:GridView>
div>
form>
---------------------------
重点在于：
设置链接按钮显示的内容：DataTextField="studentno"
设置链接按钮显示的内容的样式DataTextFormatString="[{0}]"
设置链接按钮超链接字符串的参数列表DataNavigateUrlFields="studentno,chinese"
设置链接按钮超链接字符串
DataNavigateUrlFormatString="~/Default8.aspx?studentno={0}&chinese={1}" Target="_top"
---------------------------
效果如图：
