Crystal Reports报告源问题 [英] Crystal Reports Report Source problem

问题描述

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared; 


namespace Reports
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnSimpleReport_Click(object sender, EventArgs e)
        {
            NorthwindDataSet dts = new NorthwindDataSet();
            NorthwindDataSetTableAdapters.CustomersTableAdapter dta = new NorthwindDataSetTableAdapters.CustomersTableAdapter();
            dta.Fill(dts.Customers);
            RPTsimple report = new RPTsimple(); //create instance
            report.SetDataSource(dts);
            crystalReportViewer1.ReportSource = report; //Problem Line
        }

为什么ReportSource在visual studio中有下划线。我正在使用C＃framework 3.5

查看//问题行

我的错误：

Why is ReportSource underlines in visual studio. Im using C# framework 3.5
look at //problem line
my error:

'Microsoft.Reporting.WinForms.ReportViewer' does not contain a definition for 'ReportSource' and no extension method 'ReportSource' accepting a first argument of type 'Microsoft.Reporting.WinForms.ReportViewer' could be found (are you missing a using directive or an assembly reference?)

推荐答案

我认为

I think

report.SetDataSource(dts);

这是问题。

this is the problem line.

report.SetDataSource(dts.Tables[0]);

试试这个。

Try this.

使用CrystalDecisions.CrystalReports.Engine;

使用CrystalDecisions.Shared;



.....

...





crystalReportViewer1。 ReportSource =报告;

为什么......总是=>缺少使用直接...参考..

问题与.ReportSource无法定义...

?????

一些身体帮助我！

using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;

.....
...


crystalReportViewer1.ReportSource = report;
Why ... always => missing using direct ... reference..
problem with .ReportSource not definition...
?????
some body help me!

我遇到了同样的问题。当我在我的aspx页面（不是代码隐藏文件）上拖放CrystalReportViewer而不是从工具箱的报告部分拖放ReportViewer控件时，没有错误

I had a same problem. When i drag and drop CrystalReportViewer1 on my aspx page(not code behind file) instead of ReportViewer control from Reporting section of toolbox, there was no error that the

'Microsoft.Reporting.WinForms.ReportViewer' does not contain a definition for 'ReportSource' and no extension method 'ReportSource' accepting a first argument of type 'Microsoft.Reporting.WinForms.ReportViewer' could be found (are you missing a using directive or an assembly reference?)
