How do you change the protection level of a control within a usercontrol when said usercontrol is in a WPF usercontrol library?
In my solution, I have a a WPF UserControl library project that contains several UserControl objects.
Ive got a WPF Application project that contains a window object that uses two user controls - one is a toolbar (in the library project), and the other is a general content control in the application project.
I'm trying to add a button handler for a toolbar button. Because the controls inside a user control are all marked as "internal", I can't add a button handler in the "code behind" (what a stupid f*ckin way to have to say "real goddamn code", but I gigress).
So how do I accomplish what I want if all the frakking controls are internal?

You probably want your toolbar button to be bound to a command:
Open...
If it is a standard command, such as file open, use the commands provided by the ApplicationCommands class as shown above. If not, create and register your own new command (must be static).
In your app code, bind a method to that command. That method will get called when the command "is raised". It's just like registering for an event, with one level of decoupling.
This "decoupling" between the UI and the rest of the app is a key idea of WPF. In WPF, you should not be directly linking to event handlers of a specific button. By using a command, the UI can be changed from a button to some other control type, and the command is still the same. If you wiered up directly to the event handler, then if you change the button to another type, you would have to find all places that event was being handled, and then change the event handler signature.
I've only been using WPF for about 2 months, and I share your frustration. You must see the WPF light  resistance is futile...

Are you sure? We've been doing that for years before WPF came along. I thought there was more to it than that.

John - you can change the visibility of controls by specifying a FieldModifier, e.g. x:FieldModifier="public".

Yeah, I found that out, but somehow it didn't seem to be the "WPF way". The guy before you posted what I think might be the "WPF way". Have I mentioned how badly WPF sucks yet today?

I don't think you have at least not enough. I think you're starting to get into a love\ hate relationship with it. Just ask it out on a date already!!!

I actually do love hating it because in my own way, I'm justified in hating it.

I'm still standing on the sidelines watching. Sort of like the jury is still out, you know? I mean the historical perspective on WPF could end up being, "The best implementation of a bad idea ever". Of course there can be no doubt that my perspective will be proved wrong one day when computers just do what we want them to do without us having to tell them what to do.  ![Jig | [Dance]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/jig.gif)

This doesn't work with TextBoxes, TextBlocks or Labels.

Hi all,
I have a silverlight project folder and need to refer an file inside a folder(named as "MyFolder") which is at the same level of the silverlight projec, but not inside the solution.
I want to get the path for that folder so that I can access the contents of "MyFolder"?
I have tried :
string path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
but its giving me "Access denied exception"
I want to do it from xaml.cs file....
Can anybody know how to get the project path so that I can access the "MyFolder"?
Thanks in advance,

Silverlight runs on the client end - it has no knowledge of absolute
physical paths on what I'm assuming is your server.

Hi salon,
Can you tell about your solution for this problem?
Thanks & Best Regards,

hi salon
how do you solved your problem of fetching the local path.
I ran into an issue while implementing BITS, the problem is while creating a job in BITS we have to send the local path (physical path like c:/doc/sample.txt) but Silverlight will not give us the physical path or fullpath. It says access denied.
How to get the physical path or fullpath of the file in silverlight?
Thanks

Hello everyone,
For small research project of my AI programme, I'm building a visualization for a multi-screen application, and 2 zones of which must be mirrored.
So basically:
- On one side I have a WPF layout with controls, data, images and animations happeling
- This content should be replicated on another screen (simply another Window)
Do you have any ideas how to achieve this? Something that could grab a frame and replicate it, like a texture brush maybe?
Thank you in advance for your answers!
Best regards,
Kel
