This is a simple and small user control that will help programmers to pass discrete parameters to Crystal Reports without writing lengthy code.


This is a simple and small user control that will help programmers to pass discrete parameters to Crystal Reports without writing lengthy code.

In this control, we are having two properties and one method:

  • ReportFileName

    This is a String parameter. This is to specify the report filename.

  • ParameterFields

    This is a String array parameter. This is to specify the parameters.

  • CrySet

    This method/function which will pass the corresponding parameter values to the report.

The Code

Before discussing the technical stuff, first we will see the pre-requirements. We need to add the following .NET references:

  • Crystaldecisions.crystalreports.engine
  • Crystaldecisions.reportsource
  • Crystaldecisions.shared


Dim pFields As New ParameterFields()
Dim pField As New ParameterField()
Dim disVal As New ParameterDiscreteValue()
Dim rVal As New ParameterRangeValue()

Assigning the Parameter Name and its Values

' parameter filed, must match with parameter in the report
pField.ParameterFieldName = "MyName"

disVal.Value = "CodeProject"     'Set the discrete Value
pField.CurrentValues.Add(disVal) 'Pass it to the parameter

With the example below, we can pass the range value:

rVal.StartValue = 150
rVal.EndValue = 200

Set the parameter fields collection into the viewer control:

crystalReportViewer1.ParameterFieldInfo = pFields

crystalReportViewer1.ReportSource = "c:\codeproject\About.rpt"

How to use this control

Step #1

Re-build the control.

Step #2

  1. Open a new project, add a crystalreportviewer control and a Button.
  2. Add this control by going to the toolbox control. Select the ‘General’ Tab, then right click on the mouse, then you will find an option in the popup as ‘Customize toolbox’. This will bring a window. Then select the tab called ‘.NET framework components’. Using the Browse button, add the UserControl. Then it will show it on the toolbox.
  3. Then add the control in our current form.
  4. Then write the following code for the Button as follows:

    Note: If necessary, change the path of the report filename.

    CryRepControl1.ReportFileName = "d:\VB.Net\AnyTest\MyProfile.rpt"
    CryRepControl1.ParameterFields(0) = "MyName;" & "J. Franklin Kennedy"
    CryRepControl1.ParameterFields(1) = "MyAge;" & "31"
    CryRepControl1.ParameterFields(2) = "DOB;" & "09/01/1973"
    CryRepControl1.ParameterFields(3) = "Married;" & "True"
    RptViewer1.ParameterFieldInfo = CryRepControl1.ParamFields
    RptViewer1.ReportSource = CryRepControl1.CrySet()
  5. Run the project.

    Note: The report ‘MyProfile.rpt’ is also in the ZIP file.
