Accessing parent data in nested repeater, in the HeaderTemplate

I have found the answer actually:

Use:

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

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

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

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")%>

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

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