SimpleLink.CreateDetail Event

Occurs every time the detail area of a SimpleLink is created.

Namespace: DevExpress.Xpf.Printing

Assembly: DevExpress.Xpf.Printing.v24.1.dll

NuGet Package: DevExpress.Wpf.Printing

Declaration

C#

public event EventHandler<CreateAreaEventArgs> CreateDetail

VB.NET

Public Event CreateDetail As EventHandler(Of CreateAreaEventArgs)

Event Data

The CreateDetail event's data class is CreateAreaEventArgs. The following properties provide information specific to this event:

Property	Description
Data	Gets or sets the object, which represents data for the area creation event.
DetailIndex	Gets or sets the index of a detail row for which the area creation event was called.

Remarks

The CreateDetail event is raised after the LinkBase.CreateDocument method is called for the SimpleLink object. This event is raised as many times as specified by the SimpleLink.DetailCount property value.

Handle the CreateDetail event to provide data for the detail area. An object containing data should be assigned to the CreateAreaEventArgs.Data property, and it will be represented using the template provided by the SimpleLink.DetailTemplate property.

Note

Do not pass visual objects (such as TextBox, Canvas, etc.) as detail area data, or the printing engine will not work as expected.

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.

    // 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);
}

    e.Data = data[e.DetailIndex];
