Accessing parent data in nested repeater, in the H

问题:

Simple question, not sure there's a simple answer!

So here's the code: (I've simplified it a lot to make it easier to read)

<asp:Repeater runat="server>
    <ItemTemplate>
        <asp:Repeater runat="server">
            <HeaderTemplate>
                <h1>My header here for: <%# OuterContainer.DataItem.MyItemName %> </h1>
            </HeaderTemplate>
            <ItemTemplate>
                My items code here
            </ItemTemplate>
        </asp:Repeater>
    </ItemTemplate>
</asp:Repeater>

How, in the HeaderTemplate - can I access the DataItem in the parent repeater?

回答1:

I have found the answer actually:

Use:

<HeaderTemplate>
    <%# ((RepeaterItem)Container.Parent.Parent).DataItem %>
</HeaderTemplate>

回答2:

Solution given by Paul didn't work for me, but this did:

<%# DataBinder.Eval(Container.Parent.Parent, "DataItem.YourProperty")%> 

回答3:

This is an old thread, but it seems proper to add:

In my case I have 2 nested ASPxGridView controls (DevExpress) and Container.Parent.Parent didn't work.

To access parent's data item from child, this is what worked for me:

<%# DataBinder.Eval(Container.NamingContainer.NamingContainer, "DataItem.DbField")%>

回答4:

If I want to retrieve a property of a parent repeater I typically do this:

<%# DataBinder.Eval(((RepeaterItem)Container.Parent.Parent).DataItem, "ThePropertyName")%>

回答5:

I have used as below. Two Repeaters act as Parent and Child.below how I get Parent value of ID Column inside Child repeater.

<%# DataBinder.Eval(((RepeaterItem)Container.Parent.Parent).DataItem, "ID") %>
