Specify Parameter Values in the Report Designer

Use the Parameters Panel to specify parameter values in the Visual Studio Report Designer:

Specify Parameter Values in Code

To specify a value for a report parameter in code, reference the parameter by name in the report’s Parameters collection and assign the value to the parameter’s Value property.

C#

using System;
// ...

// Create a report instance.
XtraReport1 report = new XtraReport1();

// Reference a parameter by name in the report's Parameters
// collection and assign a value to the parameter's Value property.
report.Parameters["parameter1"].Value = 30;

VB.NET

Imports System
' ...

' Create a report instance.
Private report As New XtraReport1()

' Reference a parameter by name in the report's Parameters
' collection and assign a value to the parameter's Value property.
Private report.Parameters("parameter1").Value = 30

Specify the parameter’s value before you generate the report’s document (call the CreateDocument() method) or invoke the report’s Print Preview.

You can also update the parameter’s value in the report’s BeforePrint event handler:

C#

private void XtraReport1_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) {
    (sender as XtraReport1).Parameters["parameter1"].Value = 42;
}

VB.NET

Private Sub XtraReport1_BeforePrint(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintEventArgs)
    TryCast(sender, XtraReport1).Parameters("parameter1").Value = 42
End Sub
