.nettiers 强类型 repeater 绑定子表字段方法

The entity property has just been added  so that you could access the child collection this way:
 
 <data:ProductsRepeater runat="server" ID="rptProducts" DataSourceID="ProductsDataSource">        
        <HeaderTemplate>
            <table border="1">
                <tr>
                    <td>Product Id</td>
                    <td>Product Name</td>
                    <td>Category</td>
                </tr>
        </HeaderTemplate>
        <ItemTemplate>
                <tr>
                    <td><%# Container.CategoryId %></td>
                    <td><%# Container.ProductName %></td>
                    <td><%# Container.Entity.CategoryIdSource.CategoryName %></td>
                </tr>
        </ItemTemplate>
        <FooterTemplate>
            </table>
        </FooterTemplate>
    </data:ProductsRepeater>
 
    <data:ProductsDataSource ID="ProductsDataSource" runat="server"
      SelectMethod="GetAll"
      EnablePaging="True"
      EnableSorting="True"
      EnableDeepLoad="True"       
  >
  <DeepLoadProperties Method="IncludeChildren" Recursive="False">
            <Types>
    <data:ProductsProperty Name="Categories"/> 
   </Types>
  </DeepLoadProperties>  
 </data:ProductsDataSource>
