绑定用户控件赋值对象(非基本数据类型)

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