如何從子代中繼器獲取父代轉發器項目？

Question

我有兩個嵌套的中繼器。意味着有一箇中繼器和裏面，我有另一箇中繼器。

我要在以下格式的數據：

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

那麼我怎樣才能做到這一點？

Answer 1

我認爲年尋找：

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！
