Hi,you need to bind the drop-down list in the repeater's "Repeater1_ItemDataBound" event.
This is the code for the .aspx:

XML

<asp:Repeater ID="Repeater1" ItemType="WebApplication26.BussinessReg" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
    <ItemTemplate>
        <%# Item.BussinessDetails %><br />
        <asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList>
    <hr />
    </ItemTemplate>
</asp:Repeater>

and this is the code-behind:

XML

public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if(!Page.IsPostBack)
        {
            Repeater1.DataSource = new List<BussinessReg> {
            new BussinessReg(){BussinessDetails = "company x", ServicesCatSub = new List<string>(){
            "a","b","c","d"
            }},
                            new BussinessReg(){BussinessDetails = "company y", ServicesCatSub = new List<string>(){
            "1","2","3","4"
            }}
            };
            Repeater1.DataBind();
        }
    }

    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        DropDownList ls = e.Item.FindControl("DropDownList1") as DropDownList;
        BussinessReg di = e.Item.DataItem as BussinessReg;
        ls.DataSource = di.ServicesCatSub;
        ls.DataBind();
    }
}
public class BussinessReg
{
    public string  BussinessDetails { get; set; }
    public List<string> ServicesCatSub { get; set; }
}

PS: I used asp.net 4.5 that's why i didn't use 'Container.DataItem' in the .aspx file.
