Getting Value out of a data repeater checkbox

I can't seem to get the checked value from the checkboxes! Is there
something wrong with the code? It loops through the repeater item
collection correctly.
HTML:
<asp:repeater id="rPrinterJobs" runat="server">
     <ItemTemplate>
          <tr>
    <td><asp:CheckBox ID="chkboxSelection" Checked=true Runat="server"
Enabled="true"></asp:CheckBox>
    <asp:Label ID="hdnStoreID" Visible="false" Text='<%#
DataBinder.Eval(Container.DataItem, "UColumn0") %>'
Runat=server></asp:Label>
    </td>
          </tr>
     </ItemTemplate>
</asp:repeater>

Code Behind:
        Dim DataItem As RepeaterItem
        Dim chkSelected As System.Web.UI.WebControls.CheckBox
        Dim strJobID As String

        Dim rc As RepeaterItemCollection = rPrinterJobs.Items
        Dim MyCheckBox As CheckBox

        For Each Item As RepeaterItem In rc
            MyCheckBox = CType(Item.FindControl("chkboxSelection"),
CheckBox)
            If MyCheckBox.Checked = True Then
                strJobID = CType(Item.FindControl("hdnStoreID"),
Label).Text
                If strJobID > "" Then
                     'Do something
                End If
            End If
        Next

Looks right.

Wha'ts not working? Is MyCheckBox.Checked always false? Are you getting
past that but strJobID is empty?

Where's this code? In a button event handler? Is viewstate on?

MyCheckBox.Checked is always false. Yes it is in a button event handler.

Something doesn't seem right. are you rebinding the repeater on postback or
is it wrapped in an if not page.ispostback ?

THe if not page.ispostback was the problem! Thanks for thinking of it!
