This example demonstrates how to use SimpleLink to print data from a non-hierarchical datasource.

To do this, perform the following steps.

• Create a DataTemplate for a single detail row and assign it to the SimpleLink.DetailTemplate property;
• Set the SimpleLink.DetailCount property to the total count of data rows in a data source;
• Handle the SimpleLink.CreateDetail event, and provide data for its CreateAreaEventArgs.Data parameter;
• Call the LinkBase.CreateDocument method to generate report pages.

Window1.xaml.cs

using System;
using System.Globalization;
using System.Windows;
using DevExpress.Xpf.Printing;
// ...
string[] data;

private void button1_Click(object sender, RoutedEventArgs e) {
    // Create an array of strings.
    data = CultureInfo.CurrentCulture.DateTimeFormat.DayNames;

    // Create a link and specify a template and detail count for it.
    SimpleLink link = new SimpleLink();
    link.DetailTemplate = (DataTemplate)Resources["dayNameTemplate"];
    link.DetailCount = data.Length;

    // Create a document.
    link.CreateDetail += new EventHandler<CreateAreaEventArgs>(link_CreateDetail);

    // Show a Print Preview window.
    PrintHelper.ShowPrintPreviewDialog(this, link);
}

void link_CreateDetail(object sender, CreateAreaEventArgs e) {
    e.Data = data[e.DetailIndex];
}

Window1.xaml.vb

Imports System
Imports System.Globalization
Imports System.Windows
Imports DevExpress.Xpf.Printing
' ...
Private data() As String

Private Sub button1_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    ' Create an array of strings.
    data = CultureInfo.CurrentCulture.DateTimeFormat.DayNames

    ' Create a link and specify a template and detail count for it.
    Dim link As New SimpleLink()
    link.DetailTemplate = DirectCast(Resources("dayNameTemplate"), DataTemplate)
    link.DetailCount = data.Length

    ' Create a document.
    AddHandler link.CreateDetail, AddressOf link_CreateDetail

    ' Show a Print Preview window.
    PrintHelper.ShowPrintPreviewDialog(Me, link)
End Sub

Private Sub link_CreateDetail(ByVal sender As Object, ByVal e As CreateAreaEventArgs)
    e.Data = data(e.DetailIndex)
End Sub

The result is shown in the following image.
