C# Windows Forms and XAML - c#

I would like to know if it is possible to combine XAML with Window Form or reverse. Also I would like to know a good place to learn how to work with both of them.
For example I want to make a XAML window on which I want to add a button with an event action wrote in C#.

Yes this is possible (both ways)
WinForms in WPF
WPF in WinForms
In both cases you add a special control that acts as a host for the other environment.

WindowsFormsHost allows you to host a Windows Forms control on a WPF page.

Use C# WPF user control in VB.NET Winforms forms [duplicate]

I have a customized WPF button control and I want to use this control with a WinForm application. I know how to use WPF user controls with WinForm using ElementHost. But I have no idea to use any single control (not a user control) with all its members with a WinForm application. Can you suggest me a good way to achieve this
Use ElementHost from System.Windows.Forms.Integration namespace
Here is detailed tutorial
Can't you wrap it to a UserControl? You can still use Host.CustomizedButton.xxx to access all the properties and methods.

Embedding a Windows Form into a WPF application

I have a Old windows form application and i don't want to convert it to wpf , i want to embed it inside my wpf application main window . How can i do this ?.
Also , How Can i transfer text between wpf and embeded WinForm using WindowsFormHost ?
You'll want to use a WindowsFormsHost. Check this tutorial out (shows how to do WPF in WinForms and vice versa).
You can use the WindowsFormsHost to add single Forms into an WPF application. If this is enough for your purposes have a look at this walkthrough.

Opening winform from wpf application programmatically

How would I go about opening a winform from a wpf application? This needs to be done through code, but the normal function
Form.Show();
will not work. I need something that will allow me to change the visibility of the form, but I am not able to access any of the gui related functions within this form.
You can work with the Windows Form the same way in a WPF application as you would from a Windows Forms application, provided you have the proper references. This should work fine:
YourForm form = new YourForm();
form.Show();
However, I would typically recommend trying to rework this to include the Windows Forms content as a UserControl within a WPF Window using a WindowsFormsHost control. This tends to be a little cleaner, since the window parenting works a bit more cleanly (since they're all WPF windows).

integration of wpf into window application

I am new in wpf application..
I am working on window application.it has many module.its one of module is in wpf which is seperate from project.so I want to integrate wpf application into window application project.
Your question is unclear. However, if you are trying to host a WPF object inside of a WinForms application, then yes, that is possible.
A good tutorial can be found here.
Assuming you mean MDI Winform for "windows Application". Here are the steps:
Create a new child Winform.
Add "WPF Interoperability" Element
Add your WPF pages to the WPF interop element
These steps only work in .NET Framework 3.0 or above, where WPF is supported.
You need to add an interop layer between the MDI application and the WPF component that you want to host. This is non-trivial.
1) Determine where the border between your managed and native code will lie. Ensure that you clearly define, delineate, and respect this border, or you will weep tears of pain. This will require use of C++/CLI in any real-world scenario.
I suggest creating a C++/CLI ref class called something like "Launcher" to act as a springboard. It exposes a native API that your native application can consume. The native application provides a pointer to your MDI window and any other req'd information.
2) Use the MDI child pointer and an HwndSource on the WPF component to drop your WPF into the native window.
3) Supply appropriate manual forwarding of window messages from MDI-land to WPF-land via a MessageHook in the HwndSource. Note that you'll manually be handling everything from WM_WINDOWPOSCHANGED to ID_HELP.
Good luck!
You can use ElementHost to add your wpf controls to windows forms. Add ElementHost control to windows form and set your wpf control as ElementHost Child property.

Is there a way to prevent WinForms controls in a WPF window from being unstyled?

I have some WinForms controls that I need to use in a WPF window. I'm able to get the controls to show up just fine and everything works as I would expect, but I'm experiencing one issue: all the WinForms controls are unstyled.
I'd like for the WinForms controls to at least use the default OS style (like I would see in a WinForms application). Is there any way to control this, or do I have to live with the controls the way they are?
The WinForms controls can't use the WPF styles, because Windows Forms doesn't understand the WPF styling and templating system.
To get them to use the "OS style" (the OS visual theme), try calling System.Windows.Forms.Application.EnableVisualStyles in your Main method. (I thought WPF handled this automatically, but I guess that's not what you're seeing.) This must be called before any controls get created!
