效果：
前台代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="rptTest.Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div class="dataTable" > <asp:HiddenField ID="hfRptColumns" runat="server" Value="receiver,expense_amount,cut_payment_amount,acutal_amount,bank_no,bank_name" /> <table cellpadding="1" cellspacing="0" border="1" style=" width:800px"> <thead> <tr> <th></th> <th > 序号 </th> <th> 收款人 </th> <th> 报销金额 </th> <th> 扣款金额 </th> <th> 实付金额 </th> <th> 银行账号 </th> <th> 开户行 </th> </tr> </thead> <tbody> <asp:Repeater ID="rptTest" runat="server"> <ItemTemplate> <tr> <td><asp:CheckBox runat="server" ID="ckBox" /></td> <td><%# Container.ItemIndex+1 %></td> <td><asp:Label ID="lblReceiver" runat="server" Text=‘<%#Eval("receiver") %>‘></asp:Label></td> <td><asp:TextBox ID="txtExpenseAmount" runat="server" Text=‘<%#Eval("expense_amount") %>‘></asp:TextBox></td> <td><asp:TextBox ID="txtCutPaymentAmount" runat="server" Text=‘<%#Eval("cut_payment_amount") %>‘></asp:TextBox></td> <td><asp:Label ID="lblAcutalAmount" runat="server" Text=‘<%#Eval("acutal_amount") %>‘></asp:Label></td> <td><asp:Label ID="lblBankNo" runat="server" Text=‘<%#Eval("bank_no") %>‘></asp:Label></td> <td><asp:Label ID="lblBankName" runat="server" Text=‘<%#Eval("bank_name") %>‘></asp:Label></td> </tr> </ItemTemplate> </asp:Repeater> </tbody> </table> <div> <asp:Button ID="btnAddNewRow" runat="server" OnClick="btnAddNewRow_Click" Text="添加一行" /> <asp:Button ID="btnDel" runat="server" Text="删除选中行" onclick="btnDel_Click" /> </div> </div> </form> </body> </html>
后台代码：
添加一行：
protected void btnAddNewRow_Click(object sender, EventArgs e) { //首先，恢复数据源 DataTable dt = DefineDataTableSchema(hfRptColumns.Value); foreach (RepeaterItem item in rptTest.Items) { DataRow newRow = dt.NewRow(); newRow["receiver"] = ((Label)item.FindControl("lblReceiver")).Text; newRow["expense_amount"] = ((TextBox)item.FindControl("txtExpenseAmount")).Text; newRow["cut_payment_amount"] = ((TextBox)item.FindControl("txtCutPaymentAmount")).Text; newRow["acutal_amount"] = ((Label)item.FindControl("lblAcutalAmount")).Text; newRow["bank_no"] = ((Label)item.FindControl("lblBankNo")).Text; newRow["bank_name"] = ((Label)item.FindControl("lblBankName")).Text; dt.Rows.Add(newRow); } //添加一行 DataRow row = dt.NewRow(); dt.Rows.Add(row); rptTest.DataSource = dt; rptTest.DataBind(); }
删除一行
protected void btnDel_Click(object sender, EventArgs e) { var arr = new System.Collections.ArrayList(); DataTable dt = DefineDataTableSchema(hfRptColumns.Value); foreach (RepeaterItem item in rptTest.Items) { var chk = item.FindControl("ckBox") as CheckBox; if (chk.Checked) continue; DataRow newRow = dt.NewRow(); newRow["receiver"] = ((Label)item.FindControl("lblReceiver")).Text; newRow["expense_amount"] = ((TextBox)item.FindControl("txtExpenseAmount")).Text; newRow["cut_payment_amount"] = ((TextBox)item.FindControl("txtCutPaymentAmount")).Text; newRow["acutal_amount"] = ((Label)item.FindControl("lblAcutalAmount")).Text; newRow["bank_no"] = ((Label)item.FindControl("lblBankNo")).Text; newRow["bank_name"] = ((Label)item.FindControl("lblBankName")).Text; dt.Rows.Add(newRow); } rptTest.DataSource = dt; rptTest.DataBind(); }
因为Repeater是服务端控件，所以用它动态增加或删除一行会刷新页面。用户体验远没有用 knockoutjs 绑定的效果好
