总结：使用Gridview的事件传递参数
一直以来，见过别人用Gridview传递参数的方法有多种，在此把一些可以借鉴的总结一下：
Code
<asp:GridView ID="gvwCaseList" runat="server" AllowSorting="True" AutoGenerateColumns="False"
DataKeyNames="case_id,create_date" OnRowCommand="gvwCaseList_RowCommand" OnRowDataBound="gvwCaseList_RowDataBound"
OnRowDeleting="gvwCaseList_RowDeleting" OnRowEditing="gvwCaseList_RowEditing"
OnSorting="gvwCaseList_Sorting" Width="100%" OnRowUpdating="gvwCaseList_RowUpdating"
OnDataBinding="gvwCaseList_DataBinding">
<Columns>
<asp:TemplateField HeaderText="案件名称" SortExpression="case_name">
<ItemTemplate>
<span title="<%#Server.HtmlEncode(Eval("case_name").ToString()) %>">
<%#ShowTitle(Eval("case_name").ToString(), 20)%>
</span>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Center" />
<ItemStyle HorizontalAlign="Left" />
</asp:TemplateField>
<asp:BoundField DataField="suspect_money" HeaderText="涉嫌金额" SortExpression="suspect_money">
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField DataField="illegal_date" DataFormatString="{0:yyyy-MM-dd}" HeaderText="案发时间"
HtmlEncode="False" SortExpression="illegal_date">
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField DataField="import_num" HeaderText="导入记录" HtmlEncode="False" SortExpression="import_num">
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField DataField="update_date" SortExpression="update_date">
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:TemplateField HeaderText="操作">
<ItemTemplate>
<asp:LinkButton ID="lkbSee" runat="server" CommandName="Edit">查看</asp:LinkButton>
<asp:LinkButton ID="lkbEdit" runat="server" CommandName="Update">修改</asp:LinkButton>
<asp:LinkButton ID="lkbDelete" runat="server" CommandName="Delete" OnClientClick="return confirm('确实要永久性地删除此文件吗？');">删除</asp:LinkButton>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
</Columns>
</asp:GridView>
