Overview

WPF and Winform are two separate platforms, but both are based on .NET version 4.0 or later, so many .NET developers begin to study how to use Winform in WPF. Microsoft has built a communication bridge between the two development platforms, and the conversion between the two has been quite mature so far. Today, we will mainly talk about how to use ComponentOne controls in these two platforms.

This paper mainly uses FlexReport .NET report control as a medium to link the two platforms.

Step 1

First of all, let's set up the basic communication channels of the two platforms. It is very simple. There are many steps on the Internet, which are mainly divided into three steps:

1. Add two references: WindowsFormsIntegration.dll (responsible for integrating WPF and Windows) and System.Windows.Forms.

two。 Add two references (in bold) to the XAML file:

To explain, what this code really works is the reference WindowsFormsIntegration.dll, and this reference System.Windows.Forms refers to the Microsoft native control in Winform, so when using ComponentOne, you can not reference it.

Let's first look at an example: using Winform in WPF through Microsoft primitive controls, the code is as follows:

WindowsFormsHost is actually a container for Winform in WPF, so all Winform controls are displayed in this container.

Setp2

As we said above, we use FlexReport as the medium for communication, then we need to prepare a few small steps:

The template of FlexReport under 1.Winform

Note: the reference here is a reference to Winform. Again, we need to quote in xmal:

Xmlns:cc11= "clr-namespace:C1.Win.FlexViewer;assembly=C1.Win.FlexViewer.4"

Add controls to the layout for report preview

Setp3

We load the report in the background

Private C1FlexReport _ report; public Window1 () {InitializeComponent (); _ report = new C1FlexReport (); / / load report definition from resources Assembly asm = Assembly.GetExecutingAssembly (); using (Stream stream = asm.GetManifestResourceStream ("WpfApp1.Resources.FlexCommonTasks.flxr")) _ report.Load (stream, "Chart2D"); / / assign report to the preview pane flexViewerPane.DocumentSource = null; flexViewerPane.DocumentSource = _ report }

Note: keep in mind that the reports here are from the Winform platform.

At this point, we have finished more than half of our work, and we are still short of the last step of turning stone into gold. Many people think that it is over here, but we have to consider the problem of ComponentOne License authorization. How to register the authorization of Winform under WPF is actually very simple, because the license mechanism of .NET is the same, we only need to register the license of the control in the same way, but manual registration is recommended here, which is very important, because if you are not careful, you will report the error of lc.exe=-1.

We all use it here.

C1FlexViewerPane

C1FlexReport

So we write the following registration information in the license file

C1.Win.FlexReport.C1FlexReport, C1.Win.FlexReport.4 C1.Win.FlexViewer.C1FlexViewerPane, C1.Win.FlexViewer.4

At this point, we are done.
