Repeater的使用

1.頁面代碼

如果要分頁，那么頁面開頭必須寫（<%@ Register Src="~/Controls/Page.ascx" TagName="Page" TagPrefix="uc1" %>）

并且分頁，頁腳<uc1:Page ID="Page2" runat="server" /> 前面的uc1要跟上面的TagPrefix值一樣

<table class="table" id="gv">
<%--頭標--%>
<thead>
?? ?<tr>
?? ??? ?<td width="50px" class="auto-style1">
?? ??? ??? ?<asp:LinkButton ID="LinkButton1" runat="server" OnClick="DeleteByChk"? OnClientClick="javascript:return checkValues('您確定要批量刪除數據嗎？')">刪除</asp:LinkButton>
?? ??? ??? ?<input type="checkbox" name="ckb" class="checkall"/>
?? ??? ?</td>
?? ??? ?<td width="50px" class="auto-style1"><span style="margin-left:20px;">序</span></td>
?? ??? ?<td width="100px" class="auto-style1">制單日期</td>

?? ??? ?<td width="50px" class="auto-style1">管理</td>
?? ?</tr>
</thead>
<%--數據的綁定--%>
<asp:Repeater runat="server" ID="rpt">

?? ??? ?<tr>
?? ??? ??? ?<td><input runat="server" id="chk" type="checkbox" value='<%#Eval("SId")%>' class="checkdelete"/></td>

2.數據的展示

private void show(){DataTable dt = System_Project_TasksBLL.GetList("");//分頁int pageNumber = 1;//頁數int pageSize = 50;//每一頁顯示數//判斷是否需要分頁if (!string.IsNullOrEmpty(Request.QueryString["page"]))pageNumber = Convert.ToInt32(Request.QueryString["page"]);
　　　　　　　//把datatable類型的數據轉換為list集合類型的數據List<System_Project_Tasks> list = new List<System_Project_Tasks>();foreach (DataRow item in dt.Rows){System_Project_Tasks data = new System_Project_Tasks();data.SId = Convert.ToInt32(item["SId"].ToString());data.SOperDate = Convert.ToDateTime(item["SOperDate"].ToString());data.SIsLock = int.Parse(item["SIsLock"].ToString());data.SName = item["SName"].ToString();data.SCode = item["SCode"].ToString();data.SConNo = item["SConNo"].ToString();data.SComId = item["SComId"].ToString();data.SLinkMan = item["SLinkMan"].ToString();data.STell = item["STell"].ToString();list.Add(data);}
　　　　　　　//篩選要顯示的數據PagedDataSource pageDataSource = new PagedDataSource(){DataSource = list,//數據源AllowPaging = true,//是否開啟分頁PageSize = pageSize,//每一頁顯示數CurrentPageIndex = pageNumber,//開始頁的位置
            };//下腳的分頁菜單的制作，pageNumber：當前頁面的頁數    pageDataSource.PageCount：獲取數據一共有多少頁this.Page2.sty("meneame", pageNumber, pageDataSource.PageCount, "?page=");//賦值this.num.InnerHtml = string.Concat("當前總計 - <span style='color:#ff0000; font-weight:bold;'>",dt.Rows.Count , "</span>條-數據");this.rpt.DataSource = pageDataSource;this.rpt.DataBind();}

3.對控件的一些基本操作

protected void Delete(object sender, EventArgs e){//查找此控件的上一個層級RepeaterItem parent = (sender as LinkButton).Parent as RepeaterItem;//在此層級下面查找控件（并不是找此層級的子集）HtmlInputCheckBox htmlInputCheckBox = parent.FindControl("chk") as HtmlInputCheckBox;//獲取chekbox的value值（id）int num = Convert.ToInt32(htmlInputCheckBox.Value);//刪除if (bll.Delete(num)){string str = HttpContext.Current.Server.HtmlEncode("您好!工程測試單刪除成功!");Response.Redirect(string.Concat("/InfoTip/Operate_Success.aspx?returnpage=", base.Request.Url.AbsoluteUri, "&tip=", str));}}protected void DeleteByChk(object sender, EventArgs e){//遍歷Repeater每一行數據foreach (RepeaterItem item in this.rpt.Items){//獲取每一行數據中的id叫chk的控件HtmlInputCheckBox htmlInputCheckBox = item.FindControl("chk") as HtmlInputCheckBox;//判斷此行數據的checkbox有沒有勾選上if (!htmlInputCheckBox.Checked){//如果沒有，那么跳過此次循環continue;}//獲取idint num = Convert.ToInt32(htmlInputCheckBox.Value);//調用bll層方法刪除
                bll.Delete(num);}string str = HttpContext.Current.Server.HtmlEncode("您好!郵件已徹底刪除!");base.Response.Redirect(string.Concat("/InfoTip/Operate_Success.aspx?returnpage=", base.Request.Url.AbsoluteUri, "&tip=", str));}
