Adding WPF controls in WinForm

I would like to use modern UI controls in my WinForms project and ideally, HandyControl. Since xaml is not used in WinForms, I followed microsoft's Hosting a WPF Composite Control in Windows Forms guide without success.

MyControls WPF UserControl MyControl1.xaml

Code:

---

<UserControl x:Class="UserControl1"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
            xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
            xmlns:local="clr-namespace:MyControls"
            mc:Ignorable="d"
            d:DesignHeight="450" d:DesignWidth="800">
    <UserControl.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/SkinDefault.xaml"/>
                <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/Theme.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </UserControl.Resources>
    <Grid>
           
    </Grid>
</UserControl>

WinForms Form1_Load

Code:

---

Dim host = New ElementHost()
host.Dock = DockStyle.Fill
Panel1.Controls.Add(host)
Dim uc = New MyControls.UserControl1
uc.InitializeComponent()
host.Child = uc

---

All references are included and the projects compile without problems, but I cannot use any WPF or HandyControl controls. Ideally I would like to add HandyControl or WPF controls in my toolbox. Any ideas?

What exactly does that mean? What exactly did you try and what exactly happened?

I created two projects. One is a wndows form named "Modern UI" and the other is a WPF User Control Library named "MyControls".

In MyControls I added the nugget package of HandyControl and edited the .xaml of the project accordingly (git).

In Modern UI I referenced MyControls.dll, PresentationCore, PresentationFramework, System.Xaml, WindowsBase and WindowsFormsIntegration. Also I edited Form1_Load according to the microsoft guide and added a panel control in my form.

The result, nothing. In Modern UI I don't see any hosted control inside the panel or any new controls in toolbox. I'm sure I've done something wrong.

Which guide do you mean? Are you talking about this:

https://docs.microsoft.com/en-us/dot...-windows-forms

That mentions using an ElementHost control on your form, which is what I thought was required. Have you done that?

This guide on Code Project also uses ElementHost:

https://www.codeproject.com/articles...e-windows-form

EDIT: I see that you are referring to an ElementHost in your code in post #1.

This doesn't necessarily solve your problem but I notice that the Code Project article creates a custom WinForms control that inherits ElementHost and does the work internally. That's a good idea, especially if you intend to use the same WPF control multiple times.

Thanks, I'll take a look at that article and the source code then. Yes, I intend to use them multiple times. WinForm controls just don't cut it for me anymore. Modern togglebutton sliders and the rest are the new standard, but I do not want to transition to WPF.
