DataGridPageControl Template

Prerequisite Knowledge
DataGrid Fundamentals: Styles, Printing, Exporting to XPS, and Using Print Preview
Advanced Concepts: Templates

To provide a new page style, a new Style whose TargetType property is set to DataGridPageControl must be assigned to the PageStyle property (see Example). To change the layout of a page, a new ControlTemplate that has a DataGridPageControl as its target type must be provided. In this template, various panels must be added and identified as the page-headers host, page-footers host, and grid host regions by setting the corresponding PrintViewBase attached properties (see Table 1 in Printing and Exporting).

Table 1: Host attached properties

Host attached property	Description
IsPageHeadersHost attached property	Identifies a panel as being the host that will contain all elements added to a page's headers through the PageHeaders property.
IsPageFootersHost attached property	Identifies a panel as being the host that will contain all elements added to a page's footers through the PageFooters property.
IsDataGridHost attached property	Identifies a Decorator as being the host that will contain a grid.

The newly-defined host panels can be located anywhere in a page regardless of their content (see Example).

Examples

All examples in this topic assume that the grid is bound to the Employees table of the Northwind database, unless stated otherwise.

The following example demonstrates how to create a style to change the layout of the printed pages by providing a new ControlTemplate that will place the page headers and footers at the top of each page and display an orange border around the area where the grid is printed.

The Print method will be called in the button's Click event, whose implementation is provided below.
