WPF Form loses it style after showing from another project

I have a C# application which contains 2 project, and when I set the first project which contains a Styled WPF Form as startup project, it has it's own style and everything is fine. But when I use this code to show that WPF from from a Windows Form Application, the first project's form loses its own style:
Window introForm;
introForm = new Client.MainWindow();
introForm.Show();
I have no idea why it happens

I have found my answer here:
https://stackoverflow.com/a/6042515/7147513
this fixed my problem:
var foo = new Uri("pack://application:,,,/MyProject;component/Resources/Styles.xaml", UriKind.RelativeOrAbsolute);
Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = foo });

How can I add a control to another control in C#?

I want to create a custom control by extending an existing control. In fact, I want to add some features to the original control. How can I another control (a control such as TextBox) to my custom control in its constructor or anywhere else?
public partial class AdvancedKnob : KnobControl
{
private DoubleInput Field_ValueControl = null;
public AdvancedKnob()
{
this.InitializeComponent();
this.Field_ValueControl = new DoubleInput();
this.Container.Add(this.Field_ValueControl); //DOES NOT WORK!!
}
}

Try this:
this.Controls.Add(this.Field_ValueControl);
For more information, go to: How to programmatically add controls to Windows forms at run time by using Visual C#

use
this.Controls.Add(control);

Is it possible to show xaml view inside windows form

I have a windows form which calls other windows form that work within my application. What I want to accomplish is to get away from this whole "windows form" thing and use WPF View (usercontrol) instead. Is there a way I can call a view to show it from my form?
ElementHost host = new ElementHost();
Cars.WPF.Views.DescriptionView descView = new Cars.WPF.Views.DescriptionView();
host.Controls.Add(descView);
host.Dock = DockStyle.Fill;
I get error: --> Argument 1: cannot convert from 'Car.WPF.Views.DescriptionView' to 'System.Windows.Forms.Control'

Add a panel in your winform (lets say panel1)
Define ElementHost at class level, Also define WPF Control at class level
ElementHost host;
Cars.WPF.Views.DescriptionView descView;
In form load event do:
host= new ElementHost();
panel1.Controls.Add(ctrlHost); //Add Element host to panel1
descView = new Cars.WPF.Views.DescriptionView();
descView.InitializeComponent();
host.Child = descView; //Instead of adding WPF control to Winform do this
Also in your project references add:
PresentationCore
PresentationFramework
WindowsBase

Yes, use Element Host.

Casting Windows.Controls.UserControl to Windows.Forms.Control

Can we cast a WPF User Control to a form control??

I'm sorry you can't. WPF works very differently internally from Winforms: Winforms uses the controls provided by the Windows OS (where each control has a window handle), where WPF uses DirectX to do the painting.
You can host WPF controls inside winforms applications (EDIT)and vice versa (with limitations) but that is perhaps not what you're after.

I tried this out:
TouchScreenWPF touchUI = new TouchScreenWPF();
ElementHost elementHost = new ElementHost();
elementHost.Child = touchUI;
Control userControl = new Control();
userControl.Controls.Add(elementHost);
The form contains the usercontrol, but does not display anything when I include a WPF User control. It works with a single button though... Am I missing something there?

Instantiate a Windows Forms control in WPF without default constructor

I am trying to host a custom Windows Forms control in WPF. My custom control does not have a public constructor, and it has a static Create() method which looks something like this:
public abstract class MyCustomControl : UserControl
{
internal MyCustomControl(...) { }
public static MyCustomControl Create(SomeEnum kind)
{
switch (kind)
{
case SomeEnum.Kind1:
return new MySuperCustomControl(...);
...
}
What I want to do is instantiate this custom control in WPF and then have it hosted in WindowsFormsHost, but I obviously can't add an abstract class:
<wfi:WindowsFormsHost Width="250" Height="150">
<my:MyCustomControl x:Name="customControl" /> <-- doesn't work
</wfi:WindowsFormsHost>
Is there a way I could add it into the "Host" via code?

You can't host control without public constructor in XAML.
You can try two way:
define name for your
WindowsFormsHost and set Child
property of WindowsFormsHost to your
instance from static Create() in C#
code. for example in initialize (or
load) method. - it is simple way.
try to bind Child property of WindowsFormsHost to Create() method.
Frankly, I don't know or this
approach will be work... but you can
try :).. how bind to method in XAML?
you can read - this or try to
look in msdn or google :)

Found it, it's the WindowsFormsHost.Child property.
