Different methods of loading Crystal Report in Crystal Report Viewer | VB .Net

This article explains different methods of loading Crystal Report in the Windows Forms from VB.NET.

1. By Report Name – This method of loading a report simply specifies the  location of the report and sets it as the reportsource for the viewer.

Dim filePath As String
filePath = Application.StartupPath + “\ReportName.rpt”
CrystalReportViewer1.ReportSource = filePath

2. By Report Object – This method of loading a report creates a new instance of the ReportDocument object from the CrystalDecisions.CrystalReports.Engine namespace and loads a report into the object by specifying the physical path to the report.

Dim filePath As String

filePath = Application.StartupPath + “\ReportName.rpt”
‘Create a new instance of the reportdocument object and load the report
Dim objReportDocument As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
objReportDocument.Load(filePath)
‘Bind the report to the viewer
CrystalReportViewer1.ReportSource = objReportDocument

3. By Untyped Report Component – This method of loading a report uses the ReportDocument component from the Components tab of the ToolBox.  When this component is added to the form, a dialogue box appears and prompts the Developer as to which type of Component to add to the form.  The options selected were ‘Untyped ReportDocument’ and a component called ReportDocument1 was added to the form.  This component acts as a proxy to the ReportDocument class.

Dim filePath As String
filePath = Application.StartupPath + “\ReportName.rpt”
Dim reportdocument1 As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
‘load the report into the report document component and set the component as the reportsource for the viewer
reportdocument1.Load(filePath)
CrystalReportViewer1.ReportSource = reportdocument1

4. By Report Object – This scenario uses a report object that has been added to the current Project.  When a report is added to a project, a class file is generated for the report making the report a strongly-typed object, in this case ‘ReportName.rpt’

‘Bind a new instance of the strongly-typed report object to the viewer
CrystalReportViewer1.ReportSource = New ReportName()

5. By Strongly-Typed Report Component – This method of loading a report uses the ReportDocument component from the Components tab of the ToolBox.  When this component is added to the form, a dialogue box appears and prompts the Developer as to which type of Component to add to the form.  The ‘Name’ option selected was the strongly-typed report that was added to the project (SolutionName.ReportName).  The option to generate a Cached Strongly-Typed Report was deselected and a report component called ‘ReportName1’ was created and added to the form.

‘ Friend WithEvents ReportName1 As SolutionName.ReportName1 -This piece of code will be there under ‘Windows forms designer generated code section.
‘Bind the strongly typed report component to the viewer
CrystalReportViewer1.ReportSource = ReportName1
