CheckBoxList取值及勾选上

            string strrighgs = "";
            for (int i = 0; i < this.cblrighgs.Items.Count; i++)
            {
                if (this.cblrighgs.Items[i].Selected == true)
                {
                    strrighgs += this.cblrighgs.Items[i].Value+"|";
                }
            }

            string str = "";
            foreach (ListItem li in cblrighgs.Items)
            {
                if (li.Selected == true)
                {
                    str += li.Value+";";
                }
            }

            Response.Write(str);
            Response.End();

数据绑定实现勾选：

            string[] strtemp = strapp.Split('|');
            foreach (string str in strtemp)
            {
                for (int i = 0; i < cblrighgs.Items.Count; i++)
                {
                    if (this.cblrighgs.Items[i].Value == str)
                    {
                        this.cblrighgs.Items[i].Selected = true;
                    }
                }
            }
