Answer 1

Only immediate properties of an instance can be displayed in a BoundField column.

One must instead use DataBinder.Eval in an itemtemplate to access the nested property instead of assigning it to a boundfield.

Example:

    
        
<%#DataBinder.Eval(Container.DataItem, "NestedClass.Name")%>
    

Alternatively, you can create a custom class which inherits BoundField and overrides GetValue to use DataBinder.Eval, as described in this blog post:
