1.把数据绑定到CheckBoxList中 protected void Page_Load(object sender, EventArgs e){if (!Page.IsPostBack){SqlConnection con = GetDBCon.GetCon();con.Open();SqlDataAdapter sda = new SqlDataAdapter("select * from admin", con);DataSet ds = new DataSet();sda.Fill(ds,"admin");this.CheckBoxList1.DataSource = ds.Tables[0];this.CheckBoxList1.DataTextField = "username";//绑定的字段名this.CheckBoxList1.DataValueField = "userid";//绑定的值this.CheckBoxList1.DataBind(); }} 2.循环读取出来 protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e){this.Lab2.Text = "";for (int i = 0; i < CheckBoxList1.Items.Count; i++){if (this.CheckBoxList1.Items[i].Selected){this.Lab2.Text = this.Lab2.Text+CheckBoxList1.Items[i].Text+".";}}} #region 设置或者得到CheckBoxList选中了的值 /**//// <summary> /// 初始化CheckBoxList中哪些是选中了的 /// </summary> /// <param name="checkList">CheckBoxList</param> /// <param name="selval">选中了的值串例如："0,1,1,2,1"</param> /// <param name="separator">值串中使用的分割符例如"0,1,1,2,1"中的逗号</param> public static string SetChecked(CheckBoxList checkList,string selval,string separator) …{ selval = separator + selval + separator; //例如："0,1,1,2,1"->",0,1,1,2,1," for(int i=0; i<checkList.Items.Count; i++) …{ […]
