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?

I am showing a WPF exe window inside another WPF application using winform host.
I have created a panel in main application and set it as child of winformhost.
mHostingPanel = new System.Windows.Forms.Panel()
{
BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle
};
mWinformHost = new WindowsFormsHost();
mWinformHost.Child = mHostingPanel;
and then I start the other window process and set hosting panel as parent.
WindowsAPI.SetParent(mProcess.MainWindowHandle, mHostingPanel.Handle);
My question is if I launch the application,Who will be rendering my Child WPF window whose parent is a winform panel.Will it be Direct-X or GDI context of Panel?
Also if I set Allowtransparency=True on child WPF application,The UI doesnt show up in hosting panel.
Found the reason.Its called airspace issue (when win32 and WPF trying to share pixels) and I dont think it can be solved by any framework API as microsoft denied it.

From what I understand so far, the InkCanvas element is in the WPF Framework. To use that, I need an ElementHost control to host the InkCanvas element. I've been to the MSDN links, but the example it gives talks of creating a WPF User Control Library project and so on. It's not that bad, but it seems a bit much to just add a control to a Winform. Is there a simpler way to do this, or am I trying to oversimplify this?
Thanks.
This should work:
ElementHost host = new ElementHost();
InkCanvas ic = new InkCanvas();
host.Child = ic;
Controls.Add(host);
As mentioned in comments, one needs to add the WPF assemblies as reference (WindowsBase, PresentationCore, PresentationFramework).
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.

I've added a regular forms control but I cannot resize it. Instead I have to resize host.
MSDN sample: Hosting a Windows Forms Control in WPF
System.Windows.Forms.Integration.WindowsFormsHost host =
new System.Windows.Forms.Integration.WindowsFormsHost();
MaskedTextBox mtbDate = new MaskedTextBox("00/00/0000");
host.Child = mtbDate;
this.grid1.Children.Add(host);
mtbDate.Width = 200; //Not work!
host.Width = 200; //Workaraound...
How can I resize the control, not the host?
This page gives a lot of information about hosting WinForms controls in WPF: http://msdn.microsoft.com/en-us/library/ms744952.aspx
The short story is that you are not supposed to resize the textbox- that will be ignored/overridden. Instead, resize the WindowsFormsHost (either in WPF or via WPF dynamic layout)
In an internet webpage , there is a constant menu usually placed on the top or left of a page from which user can navigate (They call it Iframes) ..
I would like to know if it is possible to do something like that using WinForm applications or WPF applications in c# .
At present I am simply inheriting forms from a base class . and each time the user needs to navigate , I have no option but to open up a new form with the same Peristent menu ...
Any suggestions here ?
I managed to use usercontrol to embed a form into another ..
Form1 has a userControl , Form2 embedded inside the user control .
things to note was ..
the embedded forms toplevel property should be set to false
the embedded forms FormBorderStyle should be set to none
userControl1.Controls.Clear();
Form2 f = new Form2();
f.Toplevel=flase;
f.Show();
f.TopLevel = false;
userControl1.Controls.Add(f);
You could use an MDI-container in WinForms.
see here and here for more information.
You mean like an MDI application (http://www.codeproject.com/KB/cs/myBestMDI.aspx) or just using a SplitContainer on the form? Really there are many options. WPF has ElementHost I think. Did you do any research yet? What did you find?
You could also take the toolbox approach. Have a parent program start the menu form and then other forms can use it... or it can launch from it... what ever your use case is.
Well, there should be a frame component in WPF which will give you such an option. Then you would use a "view" concept to open the WPF Pages you direct the user to.
