访问父中继DataItem属性 [英] Access Parent Repeaters DataItem Property
问题描述
我有,有一个直放站,rptReferrals,通过实体对象的列表,转诊运行的控制。该引荐对象具有到称为回答另一个表,这是得到提交给用户的答案的列表的参考。 rptReferrals将孩子中继器,rptQuestionnaire绑定到我登录时的人,这是不连接到介绍人问题的列表对象势必。
I have a control that has a Repeater, rptReferrals, that runs through a list of Entity objects, Referrals. The Referrals object has a reference to another table called Answers, which is a list of Answers that got submitted for the user. rptReferrals will bind a child repeater, rptQuestionnaire to a List of Questions for the person I am logged in with, which is not connected to the Referrals object it is bound to.
下面是ASPX code:
Here is the aspx code:
<asp:Repeater runat="server" ID="rptReferrals" OnItemDataBound="rptReferrals_OnItemDataBound">
<ItemTemplate>
//some HTML for the referral object
<asp:Repeater runat="server" ID="rptQuestionnaire" OnItemDataBound="rptQuestionnaire_OnItemDataBound">
//some HTML for displaying questions and answers
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
后端code:
protected void rptReferrals_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
//THIS IS THE ITEM THAT HAS THE LIST OF ANSWERS I NEED
var data = e.Item.DataItem as PatientReferral;
var rptQuestionnaire = e.Item.FindControl("rptQuestionnaire") as Repeater;
rptQuestionnaire.DataSource = QuestionList;
rptQuestionnaire.DataBind();
//QuestionList is a list of questions populated on page load.
// I can't bind to the property of data.Answers because not
//all questions are answered. data.Answers is only a list of
//the questions answered
}
}
protected void rptQuestionnaire_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Need to access the data.Answers object from above. HOW????
}
}
我遇到的问题是不需要的问题清单,我需要,无论用户是否回答了或不显示所有的问题。但是,如果他们没有回答这个问题,我需要显示的答案,这是附加到rptReferrals财产。
The problem I am having is that the list of questions are not required and I need to display all the questions regardless of whether the user answered it or not. But if they did answer it, I need to display the answer, which is the property attached to rptReferrals.
如何进入我的父母中继器的DataItem的属性,任何想法?我会采取任何的答案在这一点上。
Any ideas on how to access a property of the dataitem of my parent repeater? I'll take any answer at this point.
推荐答案
您可以使用的RepeaterItem $ C的
.Parent
属性$ C>控制,以您的方式工作外的RepeaterItem
(因此,它的的DataItem
)。
You can use the .Parent
attribute of the RepeaterItem
control to work your way up to the outer RepeaterItem
(and, thus, its DataItem
).
看起来这将工作:
protected void rptQuestionnaire_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Repeater currentRepeater = (Repeater)sender;
// Note that you might only need one ".Parent" here. Or you might need
// more, depends on your actual markup.
var data = ((RepeaterItem)e.Item.Parent.Parent).DataItem as PatientReferral;
// Now you have access to data.Answers from the parent Repeater
}
}
