I want to drag and drop an image on wpf application form. Can anyone provide me the code and other links for that?
If you want to D&D within a single WPF application; then this code should get you going:
Drag and Drop within WPF
If you want to D&D between WPF applications, or between another non-WPF application you've got some options, but probably the easiest is to use a bitmap transfer (it takes a bit more code, so let me know and I'll publish it).

I'm creating an experimental game (which would eventually become a map editor for a game) and I'd like to include a WPF window in the same project which would communicate with the game logic. This is not another render-xna-game-in-wpf-window question, I've read tons of those, I want to spawn a seperate WPF window independent from the XNA game window, but in the same program, in the same project. When I click Add Item and select WPF, all it gives me as an option is a User Control, no window or any other options etc. I've tried referencing PresentationCore but no lock either, am I missing something? I am not super with interoperability, so forgive me if what I tried is stupid. I also don't want "hacky" solutions (like creating a window and a borderless control and setting their location same etc) if it can't be done just tell it so, but I'm sure there is a relatively "clean" way of doing it since they'll be completely seperate, think of it like a very simple MVC: M Game Logic, V XNA Window, C WPF Window. And don't offer me Forms, I know how to go with forms, but I want WPF, I just work with WPF/XAML and WPF style controls more easily.
Being able to add a Window from the Add Item menu is controlled by a Visual Studio project type GUID. Have you tried to create the window xaml and cs files manually (or create it in another, test solution and Add Existing file)? Or just create a Window instance in code and show that? Also, Window is in PresentationFramework, not PresentationCore.
I have a windows form that handles drag and drop of images just fine.Because I cannot find a way to do this in WPF can I add the form to a page and will the drag and drop still work? The images being dragged are from outside of app.
Thanks, Betsy
You can use a WindowsFormsHost in WPF to host Windows Forms controls. This will meet your requirements. Otherwise, take a look at Drag & Drop in WPF. This is fairly easy to implement.
We have a legacy application that utilizes VB6, the Flash ActiveX control, and Flash content to display animated movies to users. For plenty of reasons we're looking to migrate away from this. I'm hoping someone out there can answer a few questions about WPF so that we can make a determination about how best to move forward.
First, a little about our current architecture and needs. The Flash content is set up as separate SWF files, where each individual SWF represents a training module with animated content. We have hundreds of these modules. Users run this software in a disconnected fashion where their local machine may or may not have ALL of these SWF files. The current application gives the user the option of downloading the SWF modules as they're needed.
Here's how we're thinking about setting up a new solution using WPF and Blend. We've written a WPF host application that can dynamically show Blend content based on button presses or whatever. And we've created a few test modules in Blend as WPF custom controls. But there are three nagging questions:
Right now we have the custom controls within the main WPF solution, but we need to make these disconnected. I've read several things about using Application.LoadComponent but I don't know if that will work for our solution.
Each of the Blend custom controls contains one or more storyboards that control the animation. As soon as I add one of the custom controls to a container in the WPF app, ALL of the storyboards automatically start "playing". How can I programatically make it so that I start/stop certain storyboards as needed?
Let's say I want to change a text label in one of the custom controls. If we're dynamically loading the custom control, how would I access one of the text labels to make such a change?
Any tips would be greatly appreciated. Loving WPF so far and hoping we can make this work and say goodbye to Flash forever!!!
There is Manage Extensibility Framework, that is a standard approach for dynamic modules.
Anyway, I haven't used it, so I would answer the questions in other way:
1) No, LoadComponent is ised for xaml files, whereas custom control consist of code and xaml. I mean, the custom control that you can add using Add->New Item->Custom Control(WPF). So you should do something like this, with reflection and ContentControl:
Assembly asm = Assembly.LoadFile(#"C:\SomeLibrary.dll");
Type type = asm.GetType("SomeNamespace.SomeControl");
var control = Activator.CreateInstance(type) as Control;
this.myContentControl.Content = control;
2) It isn't fact. You can put the storyboards into Control.Resources and launch them manually.
((Storyboard)control.Resources["myStoryboard"]).Begin(control);
3)
control.FindName("anyname") as TextBlock;
I'm creating a HUD window for inspecting biz entities in my WinForms application.
I wanted to have a completely different style of window (minimize the content area and showing only the TitleBar, no system buttons, etc) so I created a WPF application for this.
The problem is that I want this Window to 'live' inside my WinForms application. I can't just add the WPF as an OwnedForm or set the main Form as the Owner of the WPF window.
So, how can achive this?
EDIT: Thanks to pst I found the answer. Here is the snippet:
System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop(_inspector);
WindowInteropHelper inspectorHelper = new WindowInteropHelper(_inspector);
inspectorHelper.Owner = this.Handle;
_inspector.Show();
A WPF Window has a Win32-window handle/context.
See WindowInteropHelper. You can use this with Win32 (or perhaps there is WinForms support?) to set the owner window of the WPF Window. Be aware the handle does not exist until the "source initialized" (?) event.
However, using just WinForms, you may be able to customize the titlebar as much as you need (you can overwrite the drawing itself via Win32, and I think you lose all the control boxes without going this far).
There are lots of google results on this topic if you use the correct keywords.
I want to create a winforms application, this application will be similiar to the vs.net winforms designer (in certain aspects).
Basically it is going to be a blank page, where the user can drag and drop a bunch of 'widget's onto the screen. The widgets are basically custom images that I will create, that the user can resize, and it has some text on it by default which the user can double click on it to change the text.
Is this doable in winforms? If yes, what are the key aspects that I have to learn?
This is pretty easy to do in WinForms. Check out basic drag and drop. It's targeted toward 2.0. You'll use the DoDragDrop() method and capture data in drag and drop events. It requires some verbosity, but it gets the job done.
If you're keen on using WPF, take a look at MSDN's topic.
