本文主要是介绍在 MVC 4 中使用RDLC 报表,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
前期知识点
RDLC 报表
Visual Studio .NET进入2005版本以后,Crystal Report与IDE的结合更“紧密”了,至少我们看不到那个讨厌的注册窗口了。但是,Microsoft似乎并不容忍在自己的超级工具中竟然没有报表工具,于是Report Viewer Control出现了,我把它的报表称为RDLC报表
在VS .NET 2005之前,SQL Server Reporting Services中已经提供了一种被称为报表定义语言(Report Definition Language, RDL)的语言;在VS .NET 2005中,Microsoft提供了针对这种报表的设计器,并提供了在WinForm和WebForm中使用这种报表的能力。Microsoft将这种报表的后缀定为RDLC,RDL仍然是Report Definition Language的缩写,那么C代表什么呢?C代表Client-side processing,凸显了它的客户端处理能力。
这么写貌似有点长啊....简略点吧.不会RDLC的 先搞个C/S的WINDOS应用程序先练练手,教程百度.然后再搞个web winfrom 练练手,操作有点不一样.
把数据搞出来了,下面再接着干.
参考链接:
步骤:
先新建一个项目 用ASP.NET Web 窗体应用程序 创建;然后将你希望完成的报表在里面实现如下图.
界面如图:
效果如下:
MVC4
在MVC4的项目才是我们的主项目,上面那个只是为了测试RDLC功能是否正常能用,否则在MVC4中直接搞,太麻烦了.
然后拷贝文件到MVC4中.如图所示 拷贝RDLC文件夹,拷贝WebForm1.aspx
剩下就是配置一些参数了.
直接运行看下报什么错,然后根据错误配置该配置的就好了. 一般根据需要配置下面俩个其中之一.具体看界面错误有提示的.
还有路由别忘记设置了.列外不能用MVC4的访问模式
效果如下:
本地测试通过了.别急放到服务器上还有一堆错误等着你呢!!!
错误记录我都已经记录如下,自己参考着解决.
解决一下错误需要做个前期工作
想查看一下SharePoint的Microsoft.SharePoint.Library.DLL, 可是发现这个文件被安装在了GAC中. 如何才能拿到这个DLL, 反汇编一下玩玩呢?GAC的目录在c:\windows\assembly, 而这个目录是不允许你直接复制粘贴的. 为了把文件拿出来, 你需要使用命令行.
如果你使用命令行的话, 你会发现GAC的目录结构与Windows Explorer展示给你的看的目录不同.
要把文件从GAC中拿到, 你可以运行下面的命令:
C:\WINDOWS\assembly\GAC_MSIL>xcopy *.* C:\GACDLLs\ /s /r
具体程序集所在的目录也许会不同. 有可能是GAC 或者是GAC_32. 先找到你想要的文件, 然后你可能会需要从上面列出的文件夹中进行拷贝.
具体操作
win+r
cmd
cd C:\WINDOWS\assembly\GAC_MSIL>
xcopy *.* C:\GACDLLs\ /s /r
问:designer.cs 不自动生成
答:拷贝文件到MVC项目中选中文件,右键[转换为web应用程序]
问:错误 1 命名空间“Microsoft”中不存在类型或命名空间名称“Reporting”(是否缺少程序集引用?)E:\开发\装箱系统\Web_Up20151116\Web\AppPallet\AppPallet\RDLC\Default.aspx.designer.cs5733AppPallet
答:添加引用 Microsoft.ReportViewer.WebForms(引用前需要核对版本如图)

Example: <%@ Page Language="C#" Debug="true" %>or:2) Add the following section to the configuration file of your application:<configuration> <system.web> <compilation debug="true"/> </system.web></configuration>Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
