select a DropDownList value in a repeater

[dit]

Hello,

I found this piece of code for selecting a dropDownlist value in a repeater:

<aspropDownList id=ddl DataSource="<%# SourceTable %>" runat="server"
DataTextField="Name" DataValueField="Code" SelectedIndex='<%#
ListIndex((DropDownList)target,DataBinder.Eval( Container.DataItem,"Code"))
%>'></aspropDownList>

SourceTable should be protected property in your page and its type is
DataTable.
ListIndex is a helper method traverse DropDownList items and compares each
item's value with second parameter of this function. And returns item's
index.

but i can't figure out what the 'target' parameter stands for.
The following error accures: "The name 'target' does not exist in the current context".

waiting for a quick response,
thank you,
dit.
