Use Repeater nesting in asp.net to submit the selected checkbox items.

Main Code, passed the test.
Front-end:
<Asp: Repeater ID = "Repeater1" runat = "server" OnItemDataBound = "repeaterincluitemdatabound">

<ItemTemplate>
<Ul>
<Li>
<% # Eval ("DepId") %>
<% # Eval ("Name") %> </li> </ul>
<Asp: Repeater ID = "Repeater2" runat = "server">
<ItemTemplate>
<Asp: CheckBox ID = "cb" runat = "server" Text = '<% # Eval ("RealName") %>'/>
<Asp: HiddenField ID = "hidId" Value = '<% # Eval ("UserId") %> 'runat = "server"/>
</ItemTemplate>
</Asp: Repeater>
</ItemTemplate>
</Asp: Repeater>
