在n层中使用Crystal报告和linq到sql [英] Crystal report and linq to sql in n-tiers

问题描述

我在N-Tier应用程序上工作，包括Dal项目和UI项目，我在UI项目中有一个水晶报表，我想绑定在Dal项目中的一个类到UI项目中的水晶报告，我不知道怎么回事


谢谢

解决方案

只要DAL在UI中有引用（我假设它），我认为代码应该是这样的

 DAL dal =  new  DAL（）; 
 crystalReportViewer1.ReportSource = dal.tbl1; 
 crystalReportViewer1.RefreshReport（）; 
 

您必须确保正确填写tbl1并且报告预计数据会进入。

Hi,

I work on N-Tier application that consists of Dal project and UI project , i have a crystal report in UI project, i want to bind a class in Dal project to the crystal report in the UI project, i do not know how

thanks

解决方案

As long as the DAL has a reference in the UI (I am assuming it does) I would think the code should be something like this

DAL dal = new DAL();
crystalReportViewer1.ReportSource = dal.tbl1;
crystalReportViewer1.RefreshReport();

You'll have to make sure the tbl1 is filled correctly and the report expects the data coming in.
