Add NOV Button 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 code shows how to add a NOV Button Widget (control) in WPF at runtime and raise the button click event, showing a message in NOV Message Box:

using Nevron.Nov;
using Nevron.Nov.Dom;
using Nevron.Nov.Layout;
using Nevron.Nov.UI;
using Nevron.Nov.Windows;
using System.Windows;
 
namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            // Add a NOV widget inside the form
            // create the host
            NStackPanel stack = new NStackPanel();
            stack.Margins = new Nevron.Nov.Graphics.NMargins(5);
            stack.HorizontalPlacement = ENHorizontalPlacement.Left;
            stack.VerticalPlacement = ENVerticalPlacement.Top;
            stack.HorizontalSpacing = 5;
            stack.VerticalSpacing = 5;
 
            // add  text only push button
            NButton textOnlyButton = new NButton("Text only button");
            textOnlyButton.Click += new Function<NEventArgs>(OnButtonClicked);
            stack.Add(textOnlyButton);
 
            Content = new NNovWidgetHost<NStackPanel>(stack);
        }
 
        private void OnButtonClicked(NEventArgs arg1)
        {
            NMessageBox.Show("textOnlyButton.Click was raised.", "NOV Message Box");
        }
    }
}

Run the application - it should display a simple window with a "Text only button" button inside. When you click the button, the click event will be raised and will display a message inside a NOV Message Box.




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.Dom
Imports Nevron.Nov.Layout
Imports Nevron.Nov.UI
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 = {}
        NNovApplicationInstaller.Install(modules)
 
        ' create a stack panel
        Dim stack As New NStackPanel()
        stack.Margins = New Nevron.Nov.Graphics.NMargins(5)
        stack.HorizontalPlacement = ENHorizontalPlacement.Left
        stack.VerticalPlacement = ENVerticalPlacement.Top
        stack.HorizontalSpacing = 5
        stack.VerticalSpacing = 5
 
        ' add  text only push button
        Dim textOnlyButton As New NButton("Text only button")
        AddHandler textOnlyButton.Click, AddressOf textOnlyButton_Click
        stack.Add(textOnlyButton)
 
        ' create the host widget
        Content = New NNovWidgetHost(Of NStackPanel)(stack)
    End Sub
 
    Protected Sub textOnlyButton_Click(ByVal e As NEventArgs)
        NMessageBox.Show("textOnlyButton.Click was raised.", "NOV Message Box")
    End Sub
 
End Class


The NOV Message Box dialogue can replace the standard WPF Message Box (System.Windows.MessageBox) and it provides greater customization options.
