All Crystal Reports programming samples in this tutorials is based on the following database (crystaldb) . Please take a look at the database structure before you start this tutorial - Click here to see Database Structure .

In this tutorial we are taking the sum of field value of Total . This is the continuation of the previous tutorial Crystal Report Formula Field . So before we start this tutorial , take a look at the previous tutorial Crystal Report Formula Field.

Here we are taking the grand total of the Total field . The Total field is a Formula field is the result of qty X price .

In the Crystal Reports designer view right click on the Report Footer , just below the Total field and select Insert -> Summary .

Then you will get a screen , select the Total from the combo box and Sum from next Combo Box , and summary location Grand Total (Report Footer) . Click Ok button

Now you can see @Total is just below the Total field in the report Footer.

Now the designing part is over . Select the default form (Form1.vb) you created in VB.NET and drag a button and CrystalReportViewer control to your form.

Select Form's source code view and import the following :

Imports CrystalDecisions.CrystalReports.Engine

Put the following source code in the button click event

Imports CrystalDecisions.CrystalReports.Engine Imports CrystalDecisions.Shared Public Class Form1     Private Sub Button1_Click(ByVal sender As System.Object, _     ByVal e As System.EventArgs) Handles Button1.Click         Dim cryRpt As New ReportDocument         cryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt")         CrystalReportViewer1.ReportSource = cryRpt         CrystalReportViewer1.Refresh()     End Sub End Class

NOTES:

cryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt")

The Crystal Report is in your project location, there you can seeCrystalReport1.rpt . So give the full path name of report here.

When you run this program you will get the following screen.
