我有一个带有gridview的vb.net网站,目前每行都有垂直显示的考题,如下所示:
Name question answer
-----------------------
Joe question1 answer1
Joe question2 answer2
Joe question3 answer3
Jill question1 answer1
Jill question2 answer2
Jill question3 answer3
但是我想改变它,所以每个问题都是一个标题,如下所示:
Name question1 question2 question3
----------------------------------
Joe answer1 answer2 answer3
Jill answer1 answer2 answer3
这使得它更具可读性,因为每个用户只列出一次。
我已经花了大部分时间在谷歌上搜索解决方案,但实际上找不到任何有效的方法。
我想坚持使用gridview而不是重写我的所有代码。
有人有任何建议吗?
我实际上是通过其他程序员类将我的数据绑定到gridview。我正在使用这样的LINQ:
Return (From entry In report.FetchAllEntries()
Select questionID = entry.Question.QuestionID,
userID = entry.Session.User.ID,
firstName = entry.Session.User.FirstName,
lastName = entry.Session.User.LastName,
QuestionText = entry.Question.Stem,
UserResponse = entry.Response.Text,
FreeResponse = entry.ResponseText,
SessionDate = entry.Timestamp
Where SessionDate.HasValue AndAlso
SessionDate.Value >= dateField1 AndAlso
SessionDate.Value <= dateField2
Order By lastName, SessionDate, questionID
由于
答案 0 :(得分:1)
您需要使用分组来汇总结果。这应该有效:
Dim grouped =
From usersAnswers In
From result In results
Group result By result.userID Into Group
Let answers = Group.OrderBy(Function(x) x.QuestionText).ToList()
Select
answers.First().firstName,
Question1 = answers(0).UserResponse,
Question2 = answers(1).UserResponse,
Question3 = answers(2).UserResponse
