#region Repeater嵌套的Repeater中使用復選框 //Repeater嵌套-經典運用 string sqlstr1, sqlstr2; sqlstr1 = "select distinct a.ChannelID,b.ChannelName from IE_FlagGroup a left join IE_Channel b on a.ChannelID=b.ChannelID where a.isClose=0 order by a.ChannelID asc"; sqlstr2 = "select * from IE_FlagGroup where isClose=0 order by FlagID asc"; DataSet dsChannel = DBFun.dataSetTwo(sqlstr1, "Channel", sqlstr2, "Classify", "myrelation"); dsChannel.Relations.Add("myrelation", dsChannel.Tables["Channel"].Columns["ChannelID"], dsChannel.Tables["Classify"].Columns["ChannelID"], false); this.rptChannel.DataSource = dsChannel.Tables["Channel"];//綁定頂層Repeater（注意：只要綁定頂層就好，嵌套層不能綁定） this.rptChannel.DataBind(); #endregion//……略相關數據庫操作代碼#region 設置Repeater嵌套的Repeater中相應的復選框為選中狀態 string[] selTeamflag = drw["Teamflag"].ToString().Split(','); HtmlInputCheckBox checkBox; Repeater rpClass; for (int i = 0; i < this.rptChannel.Items.Count; i++) { rpClass = (Repeater)this.rptChannel.Items[i].FindControl("rptClassify"); for (int j = 0; j < rpClass.Items.Count; j++) { checkBox = (HtmlInputCheckBox)rpClass.Items[j].FindControl("chk_FlagID"); if (selTeamflag.Contains(checkBox.Value)) checkBox.Checked = true; } } #endregion#region 獲取Repeater嵌套的Repeater中的復選框所選擇的值的組合,以","隔開 string str_Teamflag = ""; HtmlInputCheckBox checkBox; Repeater rpClass; for (int i = 0; i < this.rptChannel.Items.Count; i++) { rpClass = (Repeater)this.rptChannel.Items[i].FindControl("rptClassify"); for (int j = 0; j < rpClass.Items.Count; j++) { checkBox = (HtmlInputCheckBox)rpClass.Items[j].FindControl("chk_FlagID"); if (checkBox.Checked) str_Teamflag += checkBox.Value + ","; } } if (str_Teamflag != "") { //去除最后一個字符 //str_Teamflag = str_Teamflag.Substring(0, str_Teamflag.Length - 1); str_Teamflag = str_Teamflag.Remove(str_Teamflag.Length - 1); } #endregion |
