Step 4: Create the Web Page to Display the Report

1.    Open the Default.aspx page in Design mode.

2.    Navigate to the Reporting section in the Toolbox and find the CrystalReportPartsViewer control.  Drag this control onto the Default.aspx page.

3.    Double click on the web page to view the code behind. 

4.    Add the following using statements.

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

5.    Add the following code to the Page_Load event.

ReportDocument customersReport = new ReportDocument();
 
string reportPath = Server.MapPath("Sales.rpt");
 
customersReport.Load(reportPath);
 
SetTableLocation(customersReport.Database.Tables);
 
CrystalReportPartsViewer1.ReportSource = customersReport;

6.    Add the SetTableLocation method.

private void SetTableLocation(Tables tables)
{
    ConnectionInfo connectionInfo = new ConnectionInfo();
 
    connectionInfo.ServerName = @"YOURSERVER";
    connectionInfo.DatabaseName = "AdventureWorks";
    connectionInfo.UserID = "YOURSQLLOGIN";
    connectionInfo.Password = "YOURPASSWORD";
 
    foreach (CrystalDecisions.CrystalReports.Engine.Table table in tables)
    {
        TableLogOnInfo tableLogOnInfo = table.LogOnInfo;
        tableLogOnInfo.ConnectionInfo = connectionInfo;
        table.ApplyLogOnInfo(tableLogOnInfo);
    }
}

7.    Be sure to change the ServerName, UserID, and Password to your settings.

8.    Click the Run button to start the project.  Make sure the Default.aspx page is set as the startup page.  You should see the following page.

9.    Click on the $82,425,341.28 next to the United States.  You should see the following page.

10. This displays all the states within the United States.  The Next link will allow you to scroll through the list.  If you wanted to display more than 10 at a time you can change the BatchSize property of the PartsViewer control.

11. Click on the $308,827.13 next to Idaho.  This will display the cities within Idaho with an order.  You should see the following page.

12. Click on the $9,254.26 next to Sandpoint.  This will drill into the individual detail records that make up this total.

Title: When must a company buy a license from SAP ?

Hi

If a company wants to make a commercial web-site where the CrystalReportViewer in the web-site shows reports to the customers, must the company then buy a licence and if yes what kind of license? (Please give a link).

Example:
Let us for example assume that the commercial website is made like the example in this article ("Using Crystal Reports and ASP.NET to Create Drill through Reports and Graphs"). That is an ASP.NET (C#) application that shows results to the customers with CrystalReportViewer and the ASP.NET application runs on the company's server. The company's customers pay to access and see the results on the web-site (That is how the company earn money!).

The sample was written in Visual Studio 2008 using Crystal Reports for .NET. This is the free version of Crystal Reports that comes with Visual Studio.

Title: An errror can occour in Visual Studioe 2010

When I tryed to make the example in this article in Visual Studio 2010 i got an error when running the application (not when compiling):

Parser Error Message: The base class includes the field 'CrystalReportPartsViewer1', but its type (CrystalDecisions.Web.CrystalReportPartsViewer) is not compatible with the type of control (CrystalDecisions.Web.CrystalReportPartsViewer).

I solved the error by replacing the autogenerated line in Default.aspx (when adding a CrystalReportPartsViewer):

<%@ Register assembly="CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" namespace="CrystalDecisions.Web" tagprefix="CR" %>

With this line:

<%@ Register assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" namespace="CrystalDecisions.Web" tagprefix="CR" %>


So the version number that Visual Studio 2010 inserts when adding a CrystalReportPartsViewer is wrong. In my case it should be: 13.0.2000.0


I hope this can help others...

It is a good article. Thanks.

I have a Crystal report it has dynmic information on page header when I export to excel,

only first page header shows in excel. I am using asp.net visual studio 2008 sp1.

if I export it to others format like pdf, word etc... its working fine

lets assume

page header contanis

department name = 'Operations'
date = 16-06-2010

employee name code
xyz 1
eee 2
cxy 3

here cxy is related to department 'accounts'

if we see this data in pdf or word

it will show correctly

department name = 'Operations'
date = 16-06-2010

employee name code
xyz 1
eee 2


department name = 'Accounts'
date = 16-06-2010
