ASP.NET - Checkbox in repeater to gather a string of ID's

Hi:

I have a repeater I want to add a checkbox to, then do a run through all items in the repeater and collect the ID field and pass it off to another page via the query string for use in a select statement ("SELECT BLAH FROM vwBLAH WHERE RISKID IN (request.querystring("riskstring"))

where the string will be: "3,8,23,65,87"

Here's my repeater - (disregard the riskID URL thing, it will be removed - riskID will need to be binded to the checkbox)

<asp:repeater id="rptDivision" runat="server">
<ItemTemplate>
 
 <%# DataBinder.Eval(Container.DataItem, "DivisionDesc")%>
 
 <HR>
 <asp:repeater id="rptRiskNote" runat="server" DataSource='<%# RiskNoteDataBind(DataBinder.Eval(Container.DataItem,"DivisionID")) %>'>
 <HeaderTemplate>
 <ul>
 </HeaderTemplate>
 <ItemTemplate>
 <a href='qreport-edit.aspx?q=<%# request.querystring("q")%>&riskid=<%#DataBinder.Eval(Container.DataItem, "RiskID")%>'>
 <LI>
 <%#DataBinder.Eval(Container.DataItem, "Title") & " .."%>
 </a>
 
 </ItemTemplate>
 <FooterTemplate>
 </ul>
 </FooterTemplate>
 </asp:repeater> 
</ItemTemplate>
<HeaderTemplate>
</HeaderTemplate>
<FooterTemplate>
</FooterTemplate>
</asp:repeater>

Tush's code will work. Just change this:

CheckBox ckb = new CheckBox();
ckb = (CheckBox) rptDivision.Items[i].FindControl("ckbSelect");

to this:

CheckBox ckb = (CheckBox) rptDivision.Items[i].FindControl("ckbSelect");

He gets the points if this works.

thanks - I will try it tomorrow when I go back to work. :)

ok, I was finally able to try this. I had to convert the code to VB.NEt :

Dim strID As String = ""
Dim i As Integer

For i = 0 To rptRiskNote.Items.Count - 1 Step i + 1
Dim ckb As CheckBox = CType(rptDivision.Items(i).FindControl("ckbSelect"), CheckBox)

If ckb.Checked Then
strID += (CType(rptRiskNote.Items(i).FindControl("lblID"), Label)).Text + ","
End If
Next

The checkbox is actually in rptRiskNote, not rptDivision - and VS is saying that rptRiskNote doesn't exist - possibly because it's a nested repeater?

sorry, slightly revised:

Dim strID As String = ""
Dim i As Integer

For i = 0 To rptRiskNote.Items.Count - 1 Step i + 1
Dim ckb As CheckBox = CType(rptRiskNote.Items(i).FindControl("chkSel"), CheckBox)

If ckb.Checked Then
strID += (CType(rptRiskNote.Items(i).FindControl("lblID"), Label)).Text + ","
End If
Next

Response.Write(strID)
