Here is my code:

XML

<asp:DataList ID="DataList1" runat="server" DataKeyField="iPKImage" DataSourceID="SqlDataSource2"
               RepeatLayout="Flow" RepeatDirection="Horizontal">
               <ItemTemplate>
                   <div class="thumb">
                       <a href='<%# "library_image.aspx?imageid=" & Eval("iPKImage") %>'>
                           <asp:Image ID="imgThumb" ImageUrl='<%# "showthumbnail.aspx?img=" & Eval("iPKImage") %>'

                                   </td>
                                   <td>
                                       <asp:ImageButton ID="btnDisseminate" ImageUrl="~/skins/common/icons/ico_img_disseminate.gif"

                                           CommandName="EditImage" ToolTip="Edit image" Visible="false" />
                                   </td>
                                   <td>
                                       <asp:ImageButton ID="btnDelete" ImageUrl="~/skins/common/icons/ico_del.gif" runat="server"
                                           CommandName="Delete" ToolTip="Delete image" Visible="false" />
                                   </td>
                                   <td>
                                       <asp:CheckBox  ID="cbDownload" runat="server" />
                                       <asp:HiddenField ID="hdnImageID" Value='<%# Eval("iPKImage") %>' runat="server" />
                                   </td>
                               </tr>
                           </table>
                       </div>
                   </div>
               </ItemTemplate>
           </asp:DataList>

Now, how can I find if a checkbox is checked, and if it is, select the value in the Hidden Field next to it? Thanks in advance!

If you're dealing with an ASP.NET app, tag your questions ASP.NET as well. Most questions on ASP.NET functionality have nothing to do with the language your writing the code in.

Solved myself...sorry!

VB

Dim IDList As New List(Of Int32)
        For Each dl As DataListItem In DataList1.Items
            If (CType(dl.FindControl("cbDownload"), CheckBox).Checked) Then
                IDList.Add(Int32.Parse(CType(dl.FindControl("hdnImageID"), HiddenField).Value))
            End If
        Next
