Happy Coding.....

Create Crystal Report from Visual Basic .Net 2008 using Data in DataGridView

Step 1:Prepare data in DataGridView to be placed on CrystalReport

With Me.DataGridView1

.Columns.Add("code", "Code")

.Columns.Add("name", "Name")

.Columns.Add("gender", "Gender")

.Columns.Add("address", "Address")

.EditMode = DataGridViewEditMode.EditProgrammatically

.AllowUserToAddRows = False

End With


7/18

'add data to datagridview

'example data in 10 rows

For i As Integer = 1 To 0

Me.DataGridView1.Rows.Add()

With Me.DataGridView1.Rows(i)

.Cells("code").Value = Format(i + 1, "0000")

.Cells("name").Value = "Student Name" & i + 1

.Cells("gender").Value = "M"

.Cells("address").Value = "PP"

End With

Next

Step 2:Create DataSet and DataTable for Crystal Report

o Click on Project Menu

o Click on Add New Itemo Choose DataSet (Enter DataSet name)

o Create DataTable in DataSet (Same columns in step 1)

Step 3:Create and Design Crystal Report using Data from DataTable in Step 2

o Click on ProjectMenu

o Click on Add New Item


8/18

o Choose Reporting -> Crystal Report

o Choose Create As Blank Report

o Right Clickon Database Fieldin Field Explorerof Crystal Report

o Choose Database Expert

o Choose Project Data -> ADO.Net DataSets -> (DataSet and DataTable Created in

Step 2)

o OK

o Drag Each Field in Database Fields into Crystal Report

Step 4:Create Form to View Crystal Report using CrystalReportViewer control

o Create New Form

o Draw CrystalReportViewer Control on Form

o Coding Dim dt As New DataTable

'

With dt

.Columns.Add("code")

.Columns.Add("name")

.Columns.Add("gender")

.Columns.Add("address")

End With

'

For Each dr As DataGridViewRow In Me.DataGridView1.Rows

dt.Rows.Add(dr.Cells("code").Value, dr.Cells("name").Value,

_

dr.Cells("gender").Value,dr.Cells("address").Value)

Next

Crystal Report is an application which can generate various reports from different

data sources, we can create reports, print and preview those report using it, It is

compatible with almost a developing platforms and databases, In this article you

can find useful resources for generating reports from VB.NET with Crystal Report.

We can now see how to create a sample Database and Tables and data. First wehave to create a database. Give the database name as "crystaldb"

Create a DataBase "crystaldb"

In the crystaldb database, let us create three tables OrderMaster, OrderDetails,

Product.

OrderMaster

1. OrderMaster_id

2. OrderMaster_date

3. OrderMaster_customer

4. OrderMaster_createduser

OrderDetails

1. OrderDetails_id

2. OrderDetails_masterid

3. OrderDetails_productid

4. OrderDetails_qty

Product

1. Product_id

2. Product_name3. Product_price

Now that you have a database you can start your first VB.NET Crystal Reports.

All Crystal Reportsprogramming samples in these tutorials are based upon the

following database (crystaldb, the one we created through the previous article).

Open Visual Studio .NET and select a new Visual Basic .NET Project.


11/18

Create a new Crystal Report for Product table from the above database crystalDB.

The Product Table has three fields (Product_id, Product_name, and

Product_price).

From the main menu in Visual Studio select PROJECT-->Add New Item. Then

Add New Item dialogue will appear and select Crystal Reportsfrom the dialogue

box.


12/18

Accept the default settings and click OK.

Next step is to select the appropriate connection to your database. Here we are

going to select OLEDB connection for SQL ServerSelect OLE DB ( ADO ) from Create New Connection.


13/18


14/18

Next screen is the SQL Server authentication screen. Select your Sql Server

name, enter userid, passwordand select your Database Name. Click next, Thenthe screen shows OLE DB Property values, leave it as it is, and click finish.

Then you will get your Server name under OLEDB Connectionfrom there select

database name (Crystaldb) and click the tables , then you can see all your tables

from your database.

From the tables list select Product table to the right side list.


15/18

Click Next Button

Select all fields from Product table to the right side list.


16/18

Click Finish Button. Then you can see the Crystal Reports designer window. You

can arrange the design according your requirements. Your screen looks like the

following picture.


17/18

Now the designing part is over and the next step is to call the created

Crystal Reports in VB.NET through CrystalReports Viewer control.

Select the default form (Form1.vb) you created in VB.NET and drag a button

and CrystalReportViewercontrol to your form.

Select Form's source code view and put the code on top

Imp orts CrystalDecis ions.CrystalReports.Engine

Put the following source code in the button click event

Imports CrystalDecisions.CrystalReports.Engine

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


18/18

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 Reports is in your project location, there you can

see CrystalReport1.rpt. So give the full path name of report here.

After you run the source code you will get the report like this.

Hope this article helps you to create your first Crystal Reports.
