Hey
Im generation some dynamic controls through a repeater control. Im binding through the itemdatabound event on the repeater:
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                PlaceHolder plhCheckboxMemberGroupsContainer = (PlaceHolder)e.Item.FindControl("plhCheckboxMemberGroupsContainer");
                plhCheckboxMemberGroupsContainer.EnableViewState = true;
                SiteUser siteUser = (SiteUser)e.Item.DataItem;
                Member member = new Member(siteUser.Id);
                List<MemberGroup> memberGroups = (from DictionaryEntry x in member.Groups select x.Value as MemberGroup).ToList();
                CheckBox chkMemberGroup;
                HtmlGenericControl tableCell;
                foreach (MemberGroup item in allMemberGroups)
                {
                    tableCell = new HtmlGenericControl("td");
                    chkMemberGroup = new CheckBox();
                    chkMemberGroup.ID = item.Text +"_" + siteUser.Id;
                    chkMemberGroup.EnableViewState = true;
                    if (memberGroups.Contains(item))
                    {
                        chkMemberGroup.Checked = true;
                   
                    }
                    tableCell.Controls.Add(chkMemberGroup);
                    plhCheckboxMemberGroupsContainer.Controls.Add(tableCell);
                }

            }

Im creating some checkboxes inside a placeholder, ive ensured that each checkbox gets a unique id and Im setting the viewstate explicit.

But when Im looping through these repeater controls collection I cant find them, there are gone:

             foreach (RepeaterItem item in repSiteUsers.Items)
            {

                    foreach (var control in plhCheckboxMemberGroupsContainer.Controls)
                    {
                        if (control is CheckBox)
                        {
                            // do stuff here
                        }
                    }

            }
I have to create the controls dynamic because it varies how many there are, so I cant write them static in the mark up , which I usually do. Those controls which is are static in the mark up are found, but no the dynamic created controls.

Any ideas?
