<asp:CheckBox ID="chkChoose" runat="server" /><asp:HiddenField ID="hfCategory" runat="server"
Value='<%# Eval("Id") %>' />
<%# Eval("Name") %>

public List<Guid> Selected
{
get
{
List<Guid> l = new List<Guid>();
foreach (RepeaterItem item in rptCategory.Items)
{
CheckBox cb = item.FindControl("chkChoose") as CheckBox;
if (cb != null && cb.Checked)
{
HiddenField fld = item.FindControl("hfCategory") as HiddenField;
if (fld != null)
{
Guid id = new Guid(fld.Value);
l.Add(id);
}
}
}
return l;
}
