Remarks

Examples

The following example demonstrates how to use bricks of different types to display different kinds of information in a report.

First, drop a simple button onto a form and handle its Click event. In the event handler, create a new PrintingSystem class instance. Then, create a new Link object and add it to the PrintingSystem.Links collection. Subscribe to the LinkBase.CreateDetailArea and LinkBase.CreateMarginalHeaderArea events to customize a document's detail and marginal header sections, respectively. Finally, create a document and show it in the print preview by calling the Link.ShowPreview method.

In the CreateDetailArea event handler, use the ImageBrick object to display the picture of a fish and the TextBrick object to show text containing species characteristics and its description. The code also adds a CheckBoxBrick to the document and uses a simple Brick to draw borders around specific bricks.

The CreateMarginalHeaderArea event handler uses the PageImageBrick and PageInfoBrick objects to show additional information in the page header. The PageImageBrick displays the DevExpress logo at the top of every page, while two PageInfo bricks display either the current date and time or the page number, depending on the PageInfoTextBrick.PageInfo property value.

For this example, add the "angelfish.png" and "logo.png" image files to the project. You can get the necessary files from the table below.

angelfish.png

logo.png

The following image shows the resulting report.
