Asp.net 从e.Row.DataItem分配数据

由于我是asp新手，我在基于e.Row.DataItem的分配方面遇到了一个小问题。 代码：

注意：这里e.Row.DataItem有数据（通过放置断点来查看），但当执行此操作时，不会为allTicket分配任何数据

请还原解决方案

您是否确定存储在

e.Row.DataItem

中的数据类型为

All\u Ticket

？我如何知道数据类型为All\u Ticket typee.Row.DataItem包含ticketid、appname、appid等数据。我使用ASP.NET已有一段时间了，但是我想如果你在这一行的

All\u Ticket allTicket=e.Row.DataItem作为All\u Ticket

，将鼠标悬停在

.DataItem

上，它可能会告诉你类型是什么。现在我想不起来这是否有效，但请尝试一下，至少我们可以将其作为一个选项删除。是的。dataitem中的数据与All_票证的类型相同

protected void grdStaffReport_RowDataBound(object sender, GridViewRowEventArgs e)

            Label lblTicketId = ((Label)e.Row.FindControl("lblTicketId"));
            lblTicketId.Text = "PHDT" + allTicket.TicketId;
