需求：在view视图页面中嵌入rdlc报表，rdlc的xml为动态传入的xml字符串。本项目是基于abp框架
可能出现问题：
1、rdlc报表是由asp.net的服务器控件ReportViewer来支持的，view视图不能直接使用服务器控件
2、ReportViewer需要通过aspx页面来承载，并在服务端事件中完成对控件的xml绑定、datatable绑定
3、由于是基于abp框架的项目，不能在aspx.cs后台页面中直接实例化IxxAppService接口的实现类
想达到的效果如下图：
上部分为报表的筛选区域，下部分为rdlc报表展示内容。
本次实现的思路为：
1、以view视图为主页面，在视图的上部分完成筛选信息的展示和绑定；
2、视图下部分嵌入一个iframe，iframe地址指向一个aspx页面，该页中实现ReportViewer控件的赋值和绑定
视图页面的代码参考如下：
???<div class="tab-content" style="width:100%;height:100%"> ???????<!--筛选区域--> ???????<div role="tabpanel" class="tab-pane active" id="navMenu" style="padding-top: 4px;padding-bottom: 1px;"> ???????????<div class="collapse row" id="filterHts" style="margin-right: 2px;"> ???????????</div> ???????????<div id="divTools" style="padding: 0 5px 5px;cursor: pointer;height: 33px;line-height:28px" title="点击展开搜索条件区"> ???????????????<span id="searchTools" onclick="$(‘#filterHts‘).click();" style="display:none;float:left"></span> ???????????????<span id="ExternalTools" style="float:left;"></span> ???????????????<span id="spTools" style="float:left;"></span> ???????????????<span id="spanSearch" style="float:right;line-height:12px;height:12px"><i class="fa fa-chevron-down" title="点击展开搜索条件区" aria-hidden="true" style="cursor:pointer;margin:0px 0px 0px 5px;color:#76838f"></i><i class="fa fa-chevron-up" aria-hidden="true" title="点击关闭搜索条件区" style="cursor:pointer;display:none;margin-left:5px;color:#76838f"></i></span> ???????????</div> ???????</div> ???????<div style="width:100%;height:500px"> ???????????<iframe style="width:100%;height:500px" id="ifm" src="~/Rdlc/rdlc.aspx"></iframe> ???????</div> ?????</div>
rdlc.aspx页面代码参考：
<%@ Page Language="C#" CodeBehind="rdlc.aspx.cs" Inherits="Easyman.Web.Rdlc.rdlc" %><%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> ???<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> ???<title></title></head><body> ???<form id="form1" runat="server"> ???????<div> ???????????<asp:HiddenField runat="server" ID="rpName" /> ???????????<asp:HiddenField runat="server" ID="xmlStr" /> ???????????<asp:HiddenField runat="server" ID="hidDataTable" /> ???????????<asp:ScriptManager ID="ScriptManager1" runat="server"> ???????????</asp:ScriptManager> ???????????<rsweb:ReportViewer ID="reportViewer1" runat="server" ?DocumentMapWidth="100%" Font-Names="Verdana" ????????????????Font-Size="8pt" WaitMessageFont-Names="Verdana" ?AsyncRendering="False" SizeToReportContent="True" ????????????????WaitMessageFont-Size="14pt" Width="100%" Height="100%" ZoomMode="FullPage" > ???????????</rsweb:ReportViewer> ???????</div> ???????<div style="display:none"> ???????????<asp:Button ID="SearchBtn" runat="server" OnClick="SearchBtn_Click" Text="查询" /> ???????</div> ???</form></body></html>
当点击了查询按钮之后，在视图页中实现对 rdlc.aspx页面中的隐藏控件赋值（aspx页面中隐藏控件有：xml、datatable的json数据）
隐藏控件赋值之后触发 rdlc.aspx页面查询按钮事件SearchBtn_Click
关键js如下：
???????$("#ifm").contents().find("#rpName").val($("#Name").val()); ???????$("#ifm").contents().find("#xmlStr").val(Encrypt(rdlcReport.RdlcXml)); ???????$("#ifm").contents().find("#hidDataTable").val(data.responseText); ???????//endregion ???????$("#ifm").contents().find("#SearchBtn").click();//触发RDLC子页面的查询按钮 ???????$("#ifm").contents().find("#SearchBtn").hide();rdlc.aspx页面查询后台事件方法SearchBtn_Click的代码如下：
???????protected void SearchBtn_Click(object sender, EventArgs e) ???????{ ???????????string xmlStr = EncryptHelper.AesDecrpt(this.xmlStr.Value); ???????????string tbJson = this.hidDataTable.Value; ???????????string rpName = this.rpName.Value; ???????????DataTable dt = new DataTable(); ???????????if(!string.IsNullOrEmpty( tbJson)&&tbJson!="[]") ???????????{ ???????????????dt = JSON.ToDataTable(tbJson); ???????????} ???????????reportViewer1.LocalReport.DataSources.Clear(); ???????????reportViewer1.LocalReport.DisplayName = rpName; ???????????reportViewer1.LocalReport.LoadReportDefinition(GenerateRdlc(xmlStr)); ???????????ReportDataSource reportDataSource = new ReportDataSource("DataSet1",dt); ???????????reportViewer1.LocalReport.DataSources.Add(reportDataSource); ???????????reportViewer1.LocalReport.Refresh(); ???????????????????}rdlc.aspx.cs后台的完整代码如下：
using Abp.Domain.Repositories;using Easyman.Common;using Easyman.Common.Helper;using Easyman.Domain;using Easyman.Service;using Microsoft.Reporting.WebForms;using System;using System.Collections.Generic;using System.Data;using System.IO;using System.Linq;using System.Text;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace Easyman.Web.Rdlc{ ???public partial class rdlc : System.Web.UI.Page ???{ ???????protected void Page_Load(object sender, EventArgs e) ???????{ ???????} ???????/// <summary> ???????/// 以内存流形式返回rdlc报表配置信息 ???????/// </summary> ???????/// <param name="inStr"></param> ???????/// <returns></returns> ???????public MemoryStream GenerateRdlc(string inStr) ???????{ ???????????byte[] b = Encoding.UTF8.GetBytes(inStr); ???????????MemoryStream ms = new MemoryStream(b); ???????????return ms; ???????} ???????protected void SearchBtn_Click(object sender, EventArgs e) ???????{ ???????????string xmlStr = EncryptHelper.AesDecrpt(this.xmlStr.Value); ???????????string tbJson = this.hidDataTable.Value; ???????????string rpName = this.rpName.Value; ???????????DataTable dt = new DataTable(); ???????????if(!string.IsNullOrEmpty( tbJson)&&tbJson!="[]") ???????????{ ???????????????dt = JSON.ToDataTable(tbJson); ???????????} ???????????reportViewer1.LocalReport.DataSources.Clear(); ???????????reportViewer1.LocalReport.DisplayName = rpName; ???????????reportViewer1.LocalReport.LoadReportDefinition(GenerateRdlc(xmlStr)); ???????????ReportDataSource reportDataSource = new ReportDataSource("DataSet1",dt); ???????????reportViewer1.LocalReport.DataSources.Add(reportDataSource); ???????????reportViewer1.LocalReport.Refresh(); ???????????????????} ???}}总体思路为：
1）在view视图页中实现筛选区域的值绑定和获取；
2）并在筛选条件下查询满足的datatable数据并转化为json字符串赋值给子页面rdlc.aspx的隐藏控件；
3）在view视图中给子页面rdlc.aspx隐藏控件xml配置信息赋值
4）在rdlc.aspx子页面的后台事件方法SearchBtn_Click中直接获取隐藏控件中的datatable数据和rdlc的配置xml字符串信息，然后绑定到ReportViewer控件
在mvc视图中实现rdlc报表展示
