Question

我使用嵌套的Employee数据设计了员工数据。我有两个表emp和dept .Table信息 EMP-EMPID（PK），empname，empjob，empsalary，DEPTID 部门-DEPTID（FK），DEPTNAME

我已经在部门明智地显示了数据。父级中继器显示部门表和子中继器显示了emp详细信息。我想要计算我的员工部门总数以及总薪水。就像我最后想要的那样明智计算总员工和总薪水。但是我面临的问题是计算员工和工资部门的明智。这是我的aspx.cs页面..如果你没有得到我什么是我的问题..那么看我附上一个截图

Answer 1

我在做的唯一的错误是在这个陈述中

     if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==  ListItemType.Item)

代替我应该写

 if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

现在正在运作
