Method for generating report through WPF interface and report engine

Abstract

The invention provides a method for generating a report through a WPF interface and a report engine. The structure of the report engine comprises a report template base class and a report management module; the report template base class inherits from the System.Windows.Controls.UserControl class, a public method of the report template is abstracted, and all report templates inherit from the report template base class. The public method comprises the steps of initial loading operation, loading operation, verification operation, statistics operation, search operation and print report object obtaining operation; the report management module defines four basic operations abstracted for common report functions and comprises a new report, a load report, a serialized report and a print report. The operation objects of the four operations are objects of the report template base class, and after the report template objects are transformed into the report template base class objects, the polymorphism of the operations is achieved. The WPF interface serves as a uniform interface of the report, and the design effect of 'what you see is what you get' of the report is achieved.

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
