lookAndFeel	UserLookAndFeel	A UserLookAndFeel object, specifying the look-and-feel settings applied to the Print Preview form.

Remarks

Use the ShowPreviewDialog method to invoke the Print Preview dialog showing a report document.

The ShowPreviewDialog method internally generates a report document, if it is has not yet been created.

If the document has already been created when you call the ShowPreviewDialog method, it will not be re-created. For this reason, if the report has been changed, call the XtraReport.CreateDocument or Link.CreateDocument method prior to calling the ShowPreviewDialog method.

After closing the Print Preview form, it is required to explicitly dispose of the document source (report or link) assigned to the PrintTool.

The options of the Print Preview Form are available via the PrintTool.PreviewForm property.

Example

In Windows Forms applications, you can show a document’s Print Preview by using the following methods of the ReportPrintTool: PrintTool.ShowPreview and PrintTool.ShowPreviewDialog.

This code will work in your application after you create a new report in it (named XtraReport1) and handle the Load event of the application’s main form.

C#

using System;
using System.Windows.Forms;
using DevExpress.LookAndFeel;
using DevExpress.XtraReports.UI;
// ...

private void Form1_Load(object sender, EventArgs e) {
    XtraReport1 report = new XtraReport1();

    using (ReportPrintTool printTool = new ReportPrintTool(report)) {
        // Invoke the Print Preview form modally, 
        // and load the report document into it.
        printTool.ShowPreviewDialog();

        // Invoke the Print Preview form
        // with the specified look and feel setting.
        printTool.ShowPreviewDialog(UserLookAndFeel.Default);
    }
}

VB.NET

Imports System
Imports System.Windows.Forms
Imports DevExpress.LookAndFeel
Imports DevExpress.XtraReports.UI
' ...

Private Sub Form1_Load(ByVal sender As Object, _ 
ByVal e As EventArgs) Handles MyBase.Load
    Dim report As New XtraReport1()

    Using printTool As New ReportPrintTool(report)
        ' Invoke the Print Preview form modally, 
        ' and load the report document into it.
        printTool.ShowPreviewDialog()

        ' Invoke the Print Preview form
        ' with the specified look and feel setting.
        printTool.ShowPreviewDialog(UserLookAndFeel.Default)
    End Using
End Sub
