好的,我找到了在列表视图中呈现转发器的方法,我不知道是否可以粘贴整个代码,因为它很长。结果html如下:
- 时间1
[评论:以下是列表视图中的转发器]
场景名称组名称1组名称2
S1g1Conc1g2Conc1
S2g1Conc2g2Conc2
S3g1Conc1g2Conc3
- 时间2
[评论:以下是列表视图中的转发器]
场景名称组名称1组名称2
S1g1Conc1g2Conc1
S2g1Conc2g2Conc2
S3g1Conc1g2Conc3
- 时间3
[评论:以下是列表视图中的转发器]
场景名称组名称1组名称2
S1g1Conc1g2Conc1
S2g1Conc2g2Conc2
S3g1Conc1g2Conc3
困难的部分是组的数量可以不同
我的aspx页面如下:
