如何从儿童中继器获得父中继器项目？

Question

我有两个嵌套的中继器。只有一个中继器，里面有另一个中继器。

我想要以下格式的数据：

*Transaction Id:1xasd2*
Product1  2  500
*Transaction Id:2asd21*
Product2  1  100
Product3  2  200

那我怎么能实现这个目标呢？

Answer 1

我想你一直在寻找：

Protected Sub rptMaster_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptMaster.ItemDataBound
    Dim drv As DataRowView = e.Item.DataItem
    Dim rptChild As Repeater = CType(e.Item.FindControl("rptChild"), Repeater)
    If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
            'Get TransactionID here from master repeater
            Dim lblTransactionID  As Label = drv("TransactionID")
            'bind child repeater here
            rptChild.DataSource = GetData()
            rptChild.DataBind()
    End If
End Sub

Answer 2

可以使用：

var repeater = (Repeater)sender;
var parentItem = (RepeaterItem)repeater.NamingContainer;
<Object> parentDataItem = parentItem.DataItem as <Object>;
(parentDataItem.property)

工作！
