Bind an object which has a property of type List<> to a repeater

I've created two classes in business layer.

the first one is called Users with id (int), pass (string) and privileges (Privilege) properties and the second one is called Privilege and has id (int) and privilegeName (string) properties.

I've a method that r开发者_如何学Ceturns all the users, and I use a repeater (actually I bind it to a DataList to auto create the ItemTemplate for me and then use a repeater) and it works and displays all the properties well except for my List property. it generates instead something like this System.Collections.Generic.List`1[WebApplication2.Public.BLL.Users]

I want to display it in a friendly way like "User Privileges : Privi1, Privi2" but still I want to keep the layers of my application clean and structured, for example I won't store them in a database in the same table and just store them as a text and append it.

I hope to find a simple and good solution...Thanks in advance guys =)

PS : I don't want to display the object Privilege, I want to display privilege.privilegeName

When using repeaters, there are two approaches, one is the one suggested by Bugai13: to have a custom property that displays it. This is fine for certain types of nested data.

Your other option is to just have a repeater inside a repeater, and bind it appropriately (to what would be a list assigned to your main data object, depending on how you O/R Mapper works).

You can have the code for the custom display property not in the data model, but in your presentation layer somewhere (depending on your framework/design), so it's not a "bad" thing to do that. It's up to you, with whatever "feels" best.

Just create property at your Bussiness object, and bind it:

public string PrivilegiesString
{
   get
   {
     var sb = new StringBuilder("User Privileges : ");
     foreach(var item in privileges)
     {
       sb.AppendFormat("{0}, ",item.privilegeName);
     }

     return sb.ToString();
   }
}
