Learning Crystal Reports Step by Step

Creating and Using the Crystal Reports in ASP.Net Web Site

The reports are the most important component of any application, because the

management does not need the web site pages, they require (if the web application is

about the Inventory):

How much inventory is present in the stock

How much inventory is sold out this month/week/day

How much profit is obtained and from where store

The details of the stock items

So, the reports are used for this purpose. A very useful reporting tool is available with the

Visual Studio 2005. This tool is freely available in it. It is called Crystal Report.

A Report can be developed based on any of the following database objects:

Table Views Stored Procedures (SPS)

Lets see how to design and develop these reports and how to incorporate these reports

into our web applications. For this we have to do the following tasks:

1. Creating View or Stored Procedure on which our Report will be based

2. Creating a Report based on this View or SPS

3. Designing a Form that will display the designed/developed report

4. Modifying the web.config file

5. Running the Report

Here, we create our crystal report from a View: the steps are described below,

A view is logical table, which can be used to pull the data from the multiple tables.



1. Creating View or Stored Procedure on which our Report will be based

Suppose we have the following table structure, the table name is tblEmployee

tblEmployee (EmployeeSID, EmployeeName, FatherName, Gender, QualificationSID,

DateOfBirth) & tblQualification

The QualificationSID is a foreign Key and its values is determined from the

tblQualificatin, and its structure is show here

Create the View as shown here,



Now, you will see the dialogue listing all of your database tables,



Add the tblEmployee and tblQualifiaction tables one by one for your view and press the

Close button. This will provide the following output:

The two tables are connected as you have defined the Primary-Foreign Key relationship

between these two tables. Similar to tblQualification, you add other tables e.g.

tblReligion, tblSect, tblCaster, tblDepartment etc for more detailed report.



Now,

Right Click the line between the two tables and select the option as shown,

This will ensure all of the employee data will be pulled out, although their qualification

details have not be entered.

Select the column, that is required for the Report

Press the Execute Button, the result of the View will be displayed, as shown,



Save it,

View_Employee_Details



2. Creating a Report based on this View or SPS

Add a folder for the Reports in your application

Rename the folder to Reports



Right Click the newly added folder and choose Add New Item

Select Crystal Report, change its name to crp_Employee_Details.rp

Press Add button

You will see the dialogue, if you are using Crystal Report for the first time, Check I accept the Agreement and press OK



Then you will see different options available for creating Report, leave the default setting and press OK button

Expand the Create New Connection Node and then expand the OLEDB (ADO) option as shown



You will get the Window dialogue, select the option highlighted below

Microsoft OLEDB Provider for Microsoft SQL Server and press Next Enter SQL Server credentials and press Next button

o Server Name



o User SID o Password o Select the Database Name

Press the Next Button

Press finish, this will show the dialogue,



You have noticed that HRSystem Database available there, or what so ever database you have chosen



Expand the HRSystem database and then expand the View Node and choose your required View_Employee_Details as shown,



Select it and add it to other List Box

Press Next,



Expand the Node, choose column you want to be used in your report and then

press Next btton



You can group your report data here, but now press Next button

Here, you can add or filter your report data, leave as it is and press Next

button



You can choose different format from these available formats,

Choose the format according to your requirements and press the Finish button.



The report created is shown here,

At the bottom just click the Main Report View to view the reports result



Now, formatting the report is shown here delete the EmployeeSID column

as we do not require it o Creating a Serial Number

Right click the Report and choose the option as shown here,

Insert Special Field Record No



Formatting the Date Column, select the date column and right click and then



Select the required Format and then press OK button\



Then press OK button, the result is as shown figure.

Further, you can format the report as you required, you can use the Box to

encircle the contents.



3. Designing a Form that will display the designed/developed report

Now, displaying this report is in web form. For this we add a new form.

Add a Crystal Report Viewer to the form as shown,



Add this directive, as shown using CrystalDecisions.CrystalReports.Engine;

Then, add the line in the code private ReportDocument myReportDocument; We have fix code to display any crystal report on ASP.Net web page, which is

shown here



using CrystalDecisions.CrystalReports.Engine; public partial class Display_Report : System.Web.UI.Page { private ReportDocument myReportDocument; protected void Page_Load(object sender, EventArgs e) { ReportDisplay(); } protected void ReportDisplay() { CrystalDecisions.Shared.ConnectionInfo Conn = new CrystalDecisions.Shared.ConnectionInfo(); CrystalDecisions.CrystalReports.Engine.Table myTable; CrystalDecisions.Shared.TableLogOnInfo myLog; Conn.ServerName = ConfigurationManager.AppSettings["ServerName"]; //Server Name Conn.DatabaseName = ConfigurationManager.AppSettings["DatabaseName"]; //DataBase Name Conn.UserID = ConfigurationManager.AppSettings["UserID"]; //User Name Conn.Password = ConfigurationManager.AppSettings["Password"]; //Password for (int iLog = 0; iLog < myReportDocument.Database.Tables.Count; iLog++) { myTable = myReportDocument.Database.Tables[iLog]; myLog = myTable.LogOnInfo; myLog.ConnectionInfo = Conn; myTable.ApplyLogOnInfo(myLog); myTable.Location = myLog.TableName; } // ------ Bind Report ------ CrystalReportViewer1.ReportSource = myReportDocument; CrystalReportViewer1.DataBind(); } }

Now, we have to provide the name of the Report that we want to display. Add this line in the Report_Display() Event after the line myReportDocument = new ReportDocument(); myReportDocument.Load(Server.MapPath("Reports/crp_Employee_Details.rpt"));



Final code is given here, with the report name using CrystalDecisions.CrystalReports.Engine; public partial class Display_Report : System.Web.UI.Page { private ReportDocument myReportDocument; protected void Page_Load(object sender, EventArgs e) { ReportDisplay(); } protected void ReportDisplay() { myReportDocument = new ReportDocument(); myReportDocument.Load(Server.MapPath("Reports/crp_Employee_Details.rpt")); CrystalDecisions.Shared.ConnectionInfo Conn = new CrystalDecisions.Shared.ConnectionInfo(); CrystalDecisions.CrystalReports.Engine.Table myTable; CrystalDecisions.Shared.TableLogOnInfo myLog; Conn.ServerName = ConfigurationManager.AppSettings["ServerName"]; //Server Name Conn.DatabaseName = ConfigurationManager.AppSettings["DatabaseName"]; //DataBase Name Conn.UserID = ConfigurationManager.AppSettings["UserID"]; //User Name Conn.Password = ConfigurationManager.AppSettings["Password"]; //Password



for (int iLog = 0; iLog < myReportDocument.Database.Tables.Count; iLog++) { myTable = myReportDocument.Database.Tables[iLog]; myLog = myTable.LogOnInfo; myLog.ConnectionInfo = Conn; myTable.ApplyLogOnInfo(myLog); myTable.Location = myLog.TableName; } // ------ Bind Report ------ CrystalReportViewer1.ReportSource = myReportDocument; CrystalReportViewer1.DataBind(); } }



4. Modifying the web.config file

The steps involved in creating a crystal report are as follow:

Find the section, shown below in the web.config file,

Add inside the following line before the closing tag So that the should look like as

Save all

Set the Report Page as Start page and run the site

Thats all from the todays lecture. Further, you can explore the Crystal reports as yourequire.
