#Example
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.

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];
}
