一、平时我在Repeater控件中绑定一个用户控件时，都是用户控件的属性都是基本数据类型，然后在绑定中写道：

<asp:Repeater ID="rp_company" runat="server" EnableViewState="false"><br /> <ItemTemplate><br /> <uc3:CompanyListLabel ID="CompanyListLabel1" runat="server" Pkid='<%#Eval("Pkid")%>'<br /> AccountPkid='<%#Eval("AccountPkid")%>' BusinessScope='<%#Eval("BusinessScope")%>'<br /> City='<%#Eval("City")%>' CompanyName='<%#Eval("CompanyName")%>' IndustryPkid='<%#Eval("IndustryPkid")%>'<br /> MSNNumber='<%#Eval("MSNNumber")%>' Province='<%#Eval("Province")%>' QQNumber='<%#Eval("QQNumber")%>'<br /> Summary='<%#Eval("Summary")%>' ManagementModelText='<%#Eval("ManagementModelClass.ModelDescription") %>'<br /> PhotoImageUrl='<%#Eval("PhotoImageUrl")%>'<br /> IsAuthenticate='<%#Eval("IsAuthenticate") %>' IsFeePaying='<%#Eval("IsFeePaying") %>' StarLevel='<%#Eval("StarLevel")%>'<br /> /><br /> </ItemTemplate><br /> </asp:Repeater> 

......一大把属性一一赋值，搞死人！

二、现在这样了，用户控件就一个属性，即它需要展示的那个类的对象，如：Company，Product……而不再需要将其属性一一列出了！（示例，csdn如何上传博客的附件呢？？）
