A method and report engine for generating reports using wpf interface

Abstract

The present invention provides a method and a report engine for generating reports using a WPF interface. The structure of the report engine includes two classes: a report template base class and a report management module; wherein, the report template base class inherits from System.Windows.Controls. The UserControl class abstracts the public methods of the report template, and all report templates inherit from the report template base class. The public methods include: initial loading operation, loading operation, verification operation, statistical operation, search operation, and operation of obtaining and printing report objects; the report management module defines four basic operations abstracted for commonly used report functions, including: new Reports, load reports, serialize reports, print reports. The operation objects of these four operations are the objects of the report template base class. After the report template object is transformed into the report template base class object, the polymorphism of the operation is realized. The WPF interface is used as the unified interface of the report to realize the design effect of "what you see is what you get" for the report.

Description

technical field [0001] The invention relates to the technical field of report processing, in particular to a method and a report engine for generating reports using a WPF interface. Background technique [0002] In WPF programs, there are often application scenarios for generating a large number of reports in different formats. Currently, there are two common methods for WPF programs to generate reports: one is to export data to excel to generate reports; the other is to use third-party controls to generate reports. [0003] The advantage of exporting data to excel to generate reports is that the report can be easily modified, but the disadvantage is that the modified data cannot be saved in the database, resulting in a mismatch between the modified report and the data in the database. Possible miscalculation. [0004] The advantage of using a third-party control to generate a report is that the print report is printed strictly according to the program settings, but the di...

[0003] The advantage of exporting data to excel to generate reports is that the report can be easily modified, but the disadvantage is that the modified data cannot be saved in the database, resulting in a mismatch between the modified report and the data in the database. possible miscalculation

[0004] The advantage of using a third-party control to generate a report is that the print report is printed strictly according to the program settings, but the disadvantage is that the editing function of the third-party control is weak, and the "what you see is what you get" of report modification cannot be realized. When the report does not meet the requirements, you need to return to Modify the page and re-modify; another disadvantage is that the data of each field in the report is saved in the database, and the style of the report cannot be saved

When the report template in the software changes, the report style printed again in the software may be different from the original style
