checkboxlist绑定数据方法 1.把数据绑定到CheckBoxList中 特别要注意加载顺序 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+"."; } } } 3.CheckBoxList取值 string strrighgs = ""; for (int i = 0; i < CheckBoxList1.Items.Count; i++) { if (CheckBoxList1.Items[i].Selected == true) { strrighgs += CheckBoxList1.Items[i].Value+"|"; } } string str = ""; foreach (ListItem li in CheckBoxList1.Items) { if (li.Selected == true) { str += li.Value+";"; } } Response.Write(str); Response.End(); CheckBoxList取值及勾选 string[] strtemp = strapp.Split('|'); foreach (string str in strtemp) { for (int i = 0; i < CheckBoxList1.Items.Count; i++) { if (CheckBoxList1.Items[i].Value == str) { CheckBoxList1.Items[i].Selected = true; } } }
