    {
        protected void Page_Load(object sender, EventArgs e)
        {

            var p1 = new Profile {ProfileDesc = "asdas", ProfileID = 1, ProfileStatus = 1};

            var p2 = new Profile {ProfileDesc = "asdasd", ProfileID = 2, ProfileStatus = 0};

            var p3 = new Profile {ProfileDesc = "nsadsdot", ProfileID = 3, ProfileStatus = 1};
            lista.Add(p3);

            var p4 = new Profile {ProfileDesc = "gluposti", ProfileID = 4, ProfileStatus = 1};
            lista.Add(p4);

            var p5 = new Profile {ProfileDesc = "asdaile", ProfileID = 5, ProfileStatus = 0};
            lista.Add(p5);

            var p6 = new Profile {ProfileDesc = "sdfsdf", ProfileID = 6, ProfileStatus = 1};
            lista.Add(p6);

            var p7 = new Profile {ProfileDesc = "dfsdf", ProfileID = 7, ProfileStatus = 1};
            lista.Add(p7);

            return lista;
        }

        protected void repeater_ItemDataBound(object source, RepeaterItemEventArgs e)
        {
            var taaLista = PopulateCollection();
            var someItem = (CheckBox)e.Item.FindControl("checkbox");
            var profileID = Convert.ToInt32(someItem.Attributes["data-id"]);

            foreach (var item in taaLista)
            {
                if ((item.ProfileID == profileID) && (item.ProfileStatus == 1))
                {
                    someItem.Checked = true;
                    return;
                }
                someItem.Checked = false;
            }
        }

        public class CollectionProfiles : Collection<Profile>
        {

        }
}

到目前为止，一切都很好。我正在处理 OnItemDataBound 事件以检查那些显示配置文件的文本框，其属性 Profile.StatusID 设置为 1。

现在我想捕捉所有的变化。假设用户取消选中复选框或选中以前未选中的复选框，我想将这些配置文件的 ID 保存在列表中。我该如何进行。

提前致谢。即使你给我一些想法，我也会很感激。再次感谢！

您需要在此之后处理Checkbox changed 事件，您可以确定它是否是您的集合并相应地添加或删除它
