Using a checkbox inside a repeater control

Question

I tried to do this from yesterday, but I can’t come up with a solution. I have a repeater containing a checkbox and file upload, this repeater repeats many times depending on the contents of my table. When the checkbox for downloading a file is checked, it should not check the file download. I can think of no way to do this. Any ideas? Here is the code.

Grade:

protected void UploadButton_Click(object sender, EventArgs e)
{
    String savePath = @"~/files/";
    try
    {
        foreach (RepeaterItem item in rptVrijstellingen.Items)
        {               
            FileUpload file=(FileUpload)item.FindControl("FileUpload1");
            HiddenField uid = (HiddenField)item.FindControl("hiddenid");
            CheckBox ch = (CheckBox)item.FindControl("CBupload");
            if(ch.Checked)
                Response.Write("checked");
            else
            {
                if (file.HasFile)
                {
                  String fileName = file.FileName;
                  savePath += fileName;
                  file.SaveAs(Server.MapPath(savePath + fileName));
                  tblBijlage s = new tblBijlage();
                  s.bijlageTitel = fileName;
                  s.bijlageURL = savePath;
                  s.bijlageType = "1";
                  s.fk_externvakID = Convert.ToInt16(uid.Value);
                  BLLstudent.insertFile(s);
                }
                else
                  throw new Exception("Gelieve bij alle vakken een file toe te voegen of gegeven aan mevrouw Van Orlé aan te vinken en een afspraak te maken.");
             }
             Response.Redirect("s_student_Ovrijstellingen.aspx");
          }
      }
      catch (Exception ex)
      {
          UploadStatusLabel.Text = ex.Message;                  
      }
}

View:

<!-- language: xml -->
<asp:Repeater ID="rptVrijstellingen" runat="server">
   <HeaderTemplate></HeaderTemplate>
   <ItemTemplate>
      <h2><%# Eval("tblExternVak.ExternvakNaam") %></h2>
      <asp:HiddenField ID="hiddenid" Value='<%# Eval("tblExternVak.pk_externvakID") %>' runat="server" />       
      <h4>Selecteer een bestand om te uploaden:</h4>
      Gelieve het bestand de naam te geven van het overeenkomstige vak om de verwerking vlot te laten verlopen.
       <br /><br />  <br />
       <asp:FileUpload id="FileUpload1" runat="server"></asp:FileUpload>
       <br />
       <asp:CheckBox id="CBupload" runat="server" /><asp:Label id="lblUpload" runat="server"> Geleverd aan Mevrouw Van Orlé</asp:Label>
       <hr />
    </ItemTemplate>
    <SeparatorTemplate><hr /></SeparatorTemplate>
</asp:Repeater>
<asp:Label id="UploadStatusLabel" runat="server" ForeColor="Red"></asp:Label>
<br /><br />
<asp:Button id="UploadButton" Text="volgende > " OnClick="UploadButton_Click" runat="server"></asp:Button>  

How can you see his problem with logic ... Can someone give me an example on how to solve this problem?

You are likely to become attached to the repeater during page load. Do you check PostBack?

, , , , , . , - Load:

if(!Page.IsPostBack)
{
    //Fill repeater with items here
}

, , , false.
