Here how you can deepload data on code behind.

TList<TABLENAME> entities=Data.DataRepository.TABLENAMEProvider.GetByUserId(UserId);

Data.DataRepository.TABLENAMEProvider.DeepLoad(entities, true, Data.DeepLoadType.IncludeChildren, typeof(OBJECTTODEEPLOAD));

        grdGridView.DataSource = entities;

        grdGridView.DataBind();

<asp:TemplateField HeaderText="Header info for propery"  >

            <ItemTemplate>

            <%# Eval("FKColumnNameSource.PropertyName") %>

            ItemTemplate>
