gridview索引总是-1(在线急等)

Question

gridview索引总是-1,求帮忙

Answer 1

是不是RowCommand事件中
用到了CommandArgument
看我的例子：
<asp:LinkButton ID="LinkButton_delete" runat="server" Width="30px" CommandName="DSelect" CommandArgument='<%# GridView_User.Rows.Count %>'>删除</asp:LinkButton>
if (e.CommandName == "DSelect")
            {
                string UserNo = "0";//用户名
                //******************得到是那行
                Int32 indexPos = Convert.ToInt32(e.CommandArgument);
                //******************************得到UserID
                Label lb = (Label)this.GridView_User.Rows[indexPos].FindControl("Label_UserID");
                if (lb != null)
                {
                    UserID = lb.Text.Trim();
                }
                //******************************得到UserNo
                Label ub = (Label)this.GridView_User.Rows[indexPos].FindControl("Label_UserNo");
                if (ub != null)
                {
                    UserNo = ub.Text.Trim();
                }
                //********************************执行删除操作
                OperDataBase.DeleteHn10006User(OperNo, Convert.ToInt32(UserID), UserNo);
               
            }

Answer 2

CommandArgument='<%# GridView_User.Rows.Count %>'这个是关键
否则永远得到是的－１
