I need to implement touch event on canvas. As I have to add many objects in canvas and manipulate them on touch I need to have touch event on canvas. Can any one help how can I do that in WPF?
I assume your attempting to move the objects on the canvas with user gestures? If you have Microsoft Blend take a took in the behaviors as there are ones made just for this purpose.
Sorry away from the office or I could give more exact info.

Here's what I am trying to accomplish - To create an MDI application in WPF, which can host child web applications. I am using WPF webbrowser control to render web applications. WPF inherently doesn't seem to support MDI applications, so after a bit of searching, I found this project, which uses UI controls to simulate windows and manages them inside a WPF canvas. This approach seems to work reasonably well until I start adding webbrowser control object as an MDI child.
When I add webbrowser control as an MDI child, it always appears on top of other WPF elements including other MDI child controls (as shown below). From what I understand, webbrowser control always appears on top of any other WPF object except for window (and popup). Assuming that's true, I think I need to use actual WPF window to avoid overlapping issue.
The only solution i can think of right now is to wrap WPF window inside an HwndHost object and then add that as an MDI child. However it appears that a child window cannot have title bar. That means that i need to have a window that has a dummy title bar area (just like actual window title bar) and actual content area (which will show webbrowser control) as shown below (Red border is HwndHost object).
This approach seems to solve the overlapping issue. The next thing i need to try is to let users click on the dummy title bar and drag the MDI window inside the canvas element.
Questions -
Is my understanding about WPF webbrowser control overlapping behavior right? If not, what am i missing?
Is the second approach a step in right direction for accomplishing what i want? If yes, how do i implement the drag behavior for HwndHost?
Is there any other alternate solution i can try?
Note:
Although many consider MDI not an elegant solution, I do not have a choice. (We tried alternate solutions like tabbed windows/dockable
windows, but were not well received)
I am quite new to interop programming, and do not understand the
concepts well. Please correct me if i am misunderstanding things.
Thanks!
I'm a WPF newbie and, unlike WinForms, I have a hard time to setup things in the design window.
My first obstacle is the Image control. After I drag it in the Design window it disappears and there's no way for me to edit its properties (like with the button control for example). The only way to make changes is via the XAML code which isn't very visual and intuitive.
Is there a way to keep editing the Image control in design mode? (example, move it around, select it to view its property panel, etc.)
All you should need to do is give the image control a fixed height and width and it should stay in the designer.
The best thing about the XAML is which separated from code for better re usability like asp.net. It's best you to learn different layouts such as grid, wrappanel, stackpanel etc. Then, you will feel the power of xaml. Else, you can choose the XAML building tools.

Am looking to implement a detach and popup UI behaviour in my applcation.
It basically means that I will be displaying say, a stackpanel with lot elements on the right side of my page. And on a button click, I want the stackpanel part to popup(removing its allocated space in the UI) and should be able to move it above the underlying wpf UI.
What am trying to do is that remove the stackpanel from its parent grid on button click and add it as the child of wpf popup control. But I am facing some issues doing this way. However I just want to know whether I am doing it in the correct way or do anyone have a good alternative for implementing this pin out functionality am specified here?

How about using this kinda nice control, AvalonDock, which is simulating Visual Studio's dockable components behaviors?

It will spare you the pain of developing such a specific functionality, and will have a great reusability anyway
We currently have a user control which displays a dynamic matrix of other user controls. Since it's dynamic, the view can become large, requiring the user to scroll up/down & left/right in the browser to view everything.
I would like to give the users one view of the user control with the ability to pan & zoom on it, much like the feel of this Telerik control. We own the Telerik controls and I've tried to use the Map control for our purpose, but it doesn't seem like that is going to be a good solution.
I have also placed a Canvas inside of a scroll viewer, and was able to make it pan (using scroll bars) & zoom (using Scale Tranform). This works pretty well, but it's not smooth like the Telerik control is.
So, I'm wondering what other ways there are to do this. Am I overlooking a Silverlight control that would work for me? Any input would be greatly appreciated!
I found this on CodePlex and I like their approach. I will probably be customizing it to be exactly what I want, but it's a good start. Note: It does not implement the 'throwing' capabilities.
Just checking to see if a free control with the following feature is available before I go build one.
I'm looking for a container that contains grips in which I can drag and re-size, much like a window.
Thank you,
There is a FloatableWindow control available on CodePlex, which is basically the Silverlight ChildWindow refactored to allow for non-modal use. Supports both dragging and resizing.

This might not be exactly what you are looking for, but take a look at Blacklight contols.
