Add NOV Chart control in WPF at runtime
To get started and host NOV in your WPF application, take a look at:
Getting Started with NOV in WPF using only code
The following topic shows how to add a NOV Rich Text Editor Widget (control) in WPF at runtime.
1. Reference the NOV Assemblies
Ensure that your application references the following NOV dlls:
Nevron.Nov.Presentation.dll - core NOV portable assembly;
Nevron.Nov.Host.WinBase.dll - base assembly for Windows presentation hosts (WinForm and WPF);
Nevron.Nov.Host.Wpf.dll - presentation host for WPF;
Nevron.Nov.Text.dll - assembly for the NTextModule;
These assemblies are located in NOV installation folder: C:\Program Files (x86)\Nevron Software\Nevron Open Vision VERSION\Bin\Win
2. When initializing the NOV Application, make sure to create the Text module
Open the Program.cs file and use the following code:
using Nevron.Nov;
using Nevron.Nov.Windows;
using Nevron.Nov.Text;
using System;
namespace WpfApplication1
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
// create the application
App app = new App();
// Apply license for redistribution here. You can skip this code when evaluating NOV.
NLicenseManager.Instance.SetLicense(new NLicense("LICENSE KEY"));
NModule[] modules = new NModule[] {
// TODO: Create modules here
NTextModule.Instance
};
// install Nevron Open Vision for WPF
NNovApplicationInstaller.Install(modules);
// run the application main window
app.Run(new MainWindow());
}
}
}
3. Create the Rich Text View and say Hello World
We will create a Rich Text View, a Document Block and a Section. We will then say "Hello World" in a new paragraph.
Open the MainWindow.xaml.cs file and use the following code to create the Rich Text View:
using Nevron.Nov.Text;
using Nevron.Nov.Windows;
using System.Windows;
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
// Set window size
this.Width = 620;
this.Height = 300;
// create the rich text
NRichTextView richText = new NRichTextView();
// create document block
NDocumentBlock documentBlock = richText.Content;
documentBlock.Layout = ENTextLayout.Web;
documentBlock.Sections.Clear();
// create section and paragraph saying Hello World
NSection section = new NSection();
section.Blocks.Add(new NParagraph("Hello World"));
documentBlock.Sections.Add(section);
// create NOV host
NNovWidgetHost<NRichTextView> host = new NNovWidgetHost<NRichTextView>(richText);
Content = host;
}
}
}
Run the application - it should display a simple window with a Rich Text Editor.
Using Visual Basic .NET (VB.NET)
When you create a Visual Basic WPF Application, reference the NOV Assemblies and use the following code in your MainWindow.xaml.vb:
Imports Nevron.Nov
Imports Nevron.Nov.Text
Imports Nevron.Nov.Windows
Partial Public Class MainWindow
Inherits Window
Public Sub New()
InitializeComponent()
' clear all controls from the form
' TODO: Apply license for redistribution here. You can skip this code when evaluating NOV.
NLicenseManager.Instance.SetLicense(New NLicense("LICENSE KEY"))
' Install Nevron Open Vision modules
Dim modules() As NModule = {NTextModule.Instance}
NNovApplicationInstaller.Install(modules)
' Set window size
Me.Width = 620
Me.Height = 300
' create the rich text
Dim richText As New NRichTextView()
' create document block
Dim documentBlock As NDocumentBlock = richText.Content
documentBlock.Layout = ENTextLayout.Web
documentBlock.Sections.Clear()
' create section and paragraph saying Hello World
Dim section As New NSection()
section.Blocks.Add(New NParagraph("Hello World"))
documentBlock.Sections.Add(section)
' create the host widget
Content = New NNovWidgetHost(Of NRichTextView)(richText)
End Sub
End Class
