e.CommandArgument值总是为空，怎么一回事？

[bnc9595]

前台代码：

<asp:GridView ID="order" runat="server"  CellPadding="4" ForeColor="#333333" GridLines="None" Width="100%" AutoGenerateColumns="False" DataKeyNames="id" OnRowCommand="order_RowCommand">
        <Columns>
            <asp:BoundField HeaderText="订单ID" DataField="userid" />
            <asp:BoundField HeaderText="门票ID" DataField="voteid" />
            <asp:BoundField HeaderText="订单号" DataField="ordernum" />
            <asp:BoundField HeaderText="区域" DataField="area" />
            <asp:BoundField HeaderText="排" DataField="row" />
            <asp:BoundField HeaderText="号" DataField="num" />
            <asp:BoundField HeaderText="价格（元/张）" DataField="paid" />
            <asp:BoundField HeaderText="购票时间" DataField="buytime" />
            <asp:BoundField HeaderText="配送方式" DataField="sendforms" />
            <asp:BoundField HeaderText="付款方式" DataField="paidforms" />
            <asp:ButtonField CommandName="remove" ButtonType="Button" Text="取消"/>
            <asp:HyperLinkField DataNavigateUrlFields="userid" DataNavigateUrlFormatString="Admin_showuser.aspx?userid={0}" Text="查看订单人信息" />
        </Columns>
        </asp:GridView>

后台代码：

protected void order_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "remove")
        {
            int index = Convert.ToInt32(e.CommandArgument);
            DataTable dt = new DataTable();
            dt = adminUser1.queryorder(int.Parse(order.DataKeys[index].Values[0].ToString()));
            adminUser1.deleteorder(int.Parse(order.DataKeys[index].Values[0].ToString()));
            adminUser1.updateticket_rev(int.Parse(dt.Rows[0]["voteid"].ToString()));
            bind();
        }
    }

e.CommandArgument的值总是为0，请问这是怎么一回事呢？原来都正常的，添加了查看用户信息按钮后就不行了。

[alan0128]

dt = adminUser1.queryorder(int.Parse(order.DataKeys[e.RowIndex].Values[0].ToString()));

设置断点看，e.CommandArgument本身就是0啊

2楼的方法不行啊

[cyrix_wxm]

<asp:ButtonField CommandName="remove" ButtonType="Button" Text="取消"/>
转为
模板列试试

mark 我也不懂。。

[jerry_zuo]

LZ 你没有给值啊 。晕。

[bnc9595]

adminUser1.updateticket_rev(int.Parse(dt.Rows[0]["voteid"].ToString()));
现在这句提示：位置0处在位置 0 处没有任何行
