一、展示页面添加控件 CheckBoxList 控件

RepeatColumns ：指定一行放几个

CssClass ：添加样式 ，如不展示表格边框 ttable_border_none

       <asp:CheckBoxList ID="tbCheckBoxList_LessonTeacher" runat="server" RepeatColumns="4" CssClass="ttable_border_none">
    </asp:CheckBoxList>
 

 

二、 逻辑页面

1、给 ChenkBoxList 赋值

需要 关键字和 对应的值

 {//课程教师
            ITEM.Inherits.Bll.bllFourAdminUser _bllUser = new bllFourAdminUser();
            List<ITEM.Model.FourAdminUser> mList = _bllUser.GetListSelFourAdminUser3("AdminGuid,LoginID,UserName", base.EnterpriseGuid, " and RoleGuid in(select RoleGuid from tbFourAdminRole where RoleTypeFlag<8000)");
            this.tbCheckBoxList_LessonTeacher.DataTextField = "UserName";
            this.tbCheckBoxList_LessonTeacher.DataValueField = "AdminGuid";
            this.tbCheckBoxList_LessonTeacher.DataSource = mList;
            this.tbCheckBoxList_LessonTeacher.DataBind();
            
            //this.CheckBoxList1.Items.Add(mList[0].UserName);
            
            // for (int i=0; i<mList.Count; i++)
            // {
            //   this.CheckBoxList1.Items.Add(mList[i].UserName);
            // }
        }

2、判断是否选中

//循环
            for (int i=0;i<=this.tbCheckBoxList_LessonTeacher.Items.Count-1;i++)
            {
                //判断是否选中
                if (_classlessonsort.LessonTeacher_loginGuid.IndexOf(this.tbCheckBoxList_LessonTeacher.Items[i].Value)>=0)
                {
                    this.tbCheckBoxList_LessonTeacher.Items[i].Selected = true;
                }
            }

3、保存

        {
            //初始化
            string sGuid = string.Empty;
            string sName = string.Empty;
            for (int i=0;i<=this.tbCheckBoxList_LessonTeacher.Items.Count-1;i++)
            {
                //判断有无选中
                if (this.tbCheckBoxList_LessonTeacher.Items[i].Selected)
                {
                    //赋值，中间用 " , " 号间隔
                    string sign = sGuid == string.Empty ? "" : ",";
                    sGuid += sign + this.tbCheckBoxList_LessonTeacher.Items[i].Value;
                    sName += sign + this.tbCheckBoxList_LessonTeacher.Items[i].Text;
                }             
            }
            _classlessonsort.LessonTeacher_loginGuid = sGuid;
            _classlessonsort.LessonTeacher_loginName = sName;

        }

 

三、验证
