Access Parent Repeaters DataItem Property

asp.net, c#, nested-repeater, repeater

Solution

You can use the `.Parent` attribute of the `RepeaterItem` control to work your way up to the outer `RepeaterItem` (and, thus, its `DataItem`).

Seems like this would work:

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
    }
}

Problem

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. 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> ``` The backend 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???? } } ``` 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. Any ideas on how to access a property of the dataitem of my parent repeater? I'll take any answer at this point.
