GridView里面模板获取唯一值（如ID）

我的习惯一般都是用BUTTONFIELD或者COMMANDFIELD，用rowcommand事件，或者selectindexchange事件
如
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
       if (e.commandName = "....")
           {
            int i = Convert.toint32(e.CommandArgument.ToString()); //获取行号
            LinkButton lbt1 = ((LinkButton)GridView1.Rows.Cells[0].FindControl("LinkButton1"));
            string id = ((Label)GridView1.Rows.Cells[0].FindControl("ID")).Text;//ID绑定在一个Label上
           }
}
或者用COMMANDFIELD里面的选择
        protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            LinkButton lbt1 = ((LinkButton)GridView1.SelectedRow.Cells[0].FindControl("LinkButton1")); //SelectedRow获取行号，选择才能用
            string id = ((Label)GridView1.SelectedRow.Cells[0].FindControl("ID")).Text;//ID绑定在一个Label上
        }
GV在布局里面用的话只能用<asp:TemplateField>里面的<Template>然后就在里面绑定数据
.aspx:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BorderStyle="None"
                            BorderWidth="0px"
                            onrowcommand="GridView1_RowCommand" AllowPaging="True"
            onpageindexchanged="GridView1_PageIndexChanged" PageSize="6">
        <Columns>
            <asp:TemplateField>
            <ItemTemplate>
            <div class="mrt2">
   <ul>
   <li><p class="w542px2"><span>·</span>
            <asp:Label ID="ID" runat="server" Text='<%# Bind("Id") %>' Visible="false"></asp:Label>
            <asp:Label ID="Title_lbe" runat="server" Text='<%# Bind("Title") %>'></asp:Label>
            <asp:Label ID="Class_lbe" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
            </p>
            <p class="w135px"><span class="caozuo marglt24px caozuobg1"><span><a href="Article_mod_up.aspx?id=<%# Eval("Id") %>">编辑</a></span></span>
            <span class="caozuo caozuobg2"><span><a href="#">
                <asp:LinkButton ID="LinkButton1"
                runat="server" CommandName="del" CommandArgument='<%# Eval("Id") %>' >删除</asp:LinkButton></a></span></span></p></li>
            </ul>
      </div>
            </ItemTemplate>
            </asp:TemplateField>
        </Columns>
        </asp:GridView>

.CS：
protected void GridView1_RowCommand(object sender, CommandEventArgs e)
        {
            if (e.CommandName == "del")
            {
                string id = e.CommandArgument.ToString();
            }
        }
简短有力，和传统的获取行号法很像，但是快多了,区别在于一个是获取GV内置控件的属性，一个是自己给CommandArgument赋值
