PRICE . In these types of situations you can use the Formula Field in Crystal
Reports.
In this C# Crystal Reports tutorial we are showing that all orders with qty and
price and the total of each row , that means each in each row we are showing
the total of qty and price.
Before starting this tutorial Create a new Crystal Reports with fields
CustomerName , Order Date , Product Name and Product Price . If you do not
know how to create this report , just look the previous tutorial C# Crystal
Reports from multiple tables . In that report selecting only four fields , here we
need one more field Product->Price and one formula field Total.
After you create the above Crystal Reports, your CR designer screen is look
like the following picture :
Next step is to create a Formula Field for showing the result of Qty X Price .
Right Click the Formula Field in the Field Explorer and click New. Then you
will get an Input Message Box , type Total in textbox and click Use Editor.
Now you can see the Formula Editor screen . Here you can enter which formula
you want . Here we want the result of Qty X Price . For that we select
OrderDetails.Qty , the multipy operator (*) and Product.Price . Double click
each field for selection.
Now you can see Total Under the Formula Field . Drag the field in to the
Crystal Reports where you want to display Total.
Now the designing part is over and the next step is to call the Crystal Reports in
C# and view it in Crystal Reports Viewer control .
Select the default form (Form1.cs) you created in C# and drag a button and a
CrystalReportViewer control to your form .
You have to include CrystalDecisions.CrystalReports.Engine in your C#
Source Code.
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
Copy and paste the following source code and run your C# project
using System;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ReportDocument cryRpt = new ReportDocument();
cryRpt.Load(PUT CRYSTAL REPORT PATH
HERE\\CrystalReport1.rpt");
crystalReportViewer1.ReportSource = cryRpt;
crystalReportViewer1.Refresh();
}
}
}
cryRpt.Load(PUT CRYSTAL REPORT PATH HERE\\CrystalReport1.rpt");
The Crystal Reports file path in your C# project files location, there you can
see CrystalReport1.rpt . So give the full path name of Crystal Reports file like
c:\projects\crystalreports\CrystalReport1.rpt
