Following
example developed in Visual Studio.NET 2005. In the following code we will see
that how to use crystal report viewer in .NET.
Steps to use the crystal report viewer:-
Import
the following namespace for sql server configuration settings.
Imports
System.Data.SqlClient
'Code to
configure the database settings
'Change the
server="your server name where your sql server is running"
'database="Default" database "pubs" and sql "userid" and the "password"
Dim strConnection As
String = "server=dtpxp-skumari;database=pubs;uid=sa;pwd=;"
Dim Connection As
New SqlConnection(strConnection)
Dim strSQL As
String = "Select *
From authors"
Dim DA As
New SqlDataAdapter(strSQL, Connection)
Dim DS As
New DataSet
'Variable to
assign the report name
Dim strReportName As
String
Next we
are going to add the .rpt(Report)file. Right click on
The
Project solution --> Add -->
New Item --> .rpt File
It will
open the following window. Select the Report wizard.
![run-Crystal-Report.jpg]()
Specifying the data --> Create new connection -->
OLEDB(ADO) --> specify the data provider by following
screen.
![Create-new-connection.jpg]()
Go next till the last screen. Select the
style of report.
Now,
after creating the .rpt file we need to write the code to fill the data source.
Create a datatable in your dataset. The datatable's name
DA.Fill(DS)
'Pass the reportname to string variable
strReportName = "CrystalReport2"
'Get the Report Location
Dim strReportPath
As String =
Application.StartupPath & "\" & strReportName
& ".rpt"
'Check file exists
If Not
IO.File.Exists(strReportPath) Then
Throw (New
Exception("Unable to locate report file:" &
vbCrLf & strReportPath))
End If
'Assign the datasource and set the properties for
Report viewer
Dim rptDocument
As New
CrystalDecisions.CrystalReports.Engine.ReportDocument
rptDocument.Load(strReportPath)
rptDocument.SetDataSource(DS.Tables(0))
rptViewer.ShowRefreshButton = False
rptViewer.ShowCloseButton = False
rptViewer.ShowGroupTreeButton = False
rptViewer.ReportSource = rptDocument
