我是使用中继器以及 Datalist 的新手。

我在论坛中检查了将数据列表放置在中继器中的正确方法。下面是我创建的，但它只在我运行时显示转发器的标题

                </tr>
            </FooterTemplate>
        </asp:DataList>
    </table>
</ItemTemplate>

ItemDatabound 上的代码隐藏：

Private Sub rptrRanks_ItemDataBound(sender As Object, e As RepeaterItemEventArgs) Handles rptrRanks.ItemDataBound 
    Dim dt As DataTable 
    Dim dlRanks As DataList = DirectCast(e.Item.FindControl("dlRanks"), DataList) 
    dt = TryCast(rptrRanks.DataSource, DataTable) 
    dlRanks.DataSource = dt 
    dlRanks.DataBind() 
End Sub

对于 Datalist，我有 2 列数据。我正在寻找的结构如下：

Group
Event                                            Event
data col  data col   data col                    data col  data col   data col
data col  data col   data col                    data col  data col   data col
data col  data col   data col                    data col  data col   data col
data col  data col   data col                    data col  data col   data col

Footer information                               Footer information

请让我知道我需要更改哪些内容才能正常工作。

所有，我找到了一个做嵌套中继器的链接。我正在使用我的代码来解决这个问题。这是链接 https://www.mikesdotnetting.com/article/57/displaying-one-to-many-relationships-with-nested-repeaters
