Step 3: Create the Hyperlinks in the Report

The next step is to define the objects in the report that will appear as links to the user in a web page.  You start at the highest level of summation and define the lower level of details.  For this report we'll start at the Country level.  From within a country you can drill to a State or Province.  From within a State or Province you can drill into a City.  From within a city you can drill into the details records that make up the total.

1.    The first step is to define the starting point.  Right click on the Group #1 Name field in the GroupFooterSection1 section.  Click Copy from the pop-up menu.

2.    Right click any free space on the report and select ReportàReport Options… from the pop-up menu.

3.    The Report Options dialog should appear.  Click the Paste Link button in the Initial Report Part Settings section.

4.    The Object Name tells the viewer which object to display.  For this report we want to show the name and the total for that group so append ;SumofTotalDue1 to the Object name.  The Object Name should now be GroupNameName2;SumofTotalDue1.

5.    Click the OK button.

6.    Now that the initial view is setup you need to define what the drill down path is when the user clicks on the total that is displayed in the report.  Right click on the summation field that is in GroupFooterSection1.  Select Format Object from the pop-up menu.

7.    Click the Hyperlink tab.  Select the Report Part Drill Down option.

8.    Expand the plus sign next to GroupFooter2 and move GroupNameName4 to the Fields to Display list by clicking the > button.  Now move the SumOfTotalDue2 to the Fields to Display.

9.    Click the OK button.  When the user clicks on the field they will drill into the total field for that country.

10. Right click on the summation field in GroupFooter#2.  Select FormatObject from the pop-up menu.  Click on the Hyperlink tab and select Report Part Drilldown. 

11. Expand GroupFooter#3 and move the GroupNameCity2 and SumofTotalDue3 to the Fields to Display list.  Click the OK button.

12. Right click on the summation field in GroupFooter#3.  Select FormatObject from the pop-up menu.  Click on the Hyperlink tab and select Report Part Drilldown.

13. Expand the Details and move Name1, Name2, City1, and TotalDue1 to the Fields to Display list.  Click the OK button.

That's all you need to do in the report.  Now you need to create the web page that will display the parts.

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
