Re: Textbox do not accept accentuation

It's nice that this bug will be fixed soon in the TextBox control, thanks.

But Silverlight should provide a way to convert keystrokes into characters. It could be a KeyPressed event as in WinForms, or a static char GetChar(KeyDownEventArgs e), or even a GetCharacter member in the KeyDownEventArgs class.

Without this, it's almost impossible to figure out reliably whether the user pressed 'A' or 'a' for example (it could be a French keyboard or caps-lock could be on for example).

I have already seen several controls that end up creating a hidden TextBox, giving it the focus, and monitoring the TextChanged event just to figure out what the user wanted to do. Others (as posted above) created long look up tables that are keyboard-specific.

But these are all hacks. The real solution has to be implemented in the platform. A KeyPress event (as in WinForms) would be ideal.

Yes, this is a known bug in both Beta 1 and Beta 2 that we are addressing right now for RTM. I apologize for the inconvenience.

Sorry. False alarm.

The link is: http://www.microsoft.com/beta/downloads/

This is, actually, a very clever solution that consists in putting a HTML Element <input type="text"/> "in front" of the Silverlight object. This is a workaround that doesn't permit any thing regarding transforming and animating and makes it very dificult to move the object dynamically. It's a nice try though.

I found a Silverlight TextBox working perfectly with accented characters without any keyboard configuration.

You can check it out for yourselves here.

That's great.

KeyCode 187 and 186 otherwise it that's just great.

Thanks

Which keyboard do you use???

There is a portuguese and a portuguese brazilian layout... Please tell me your exact layout... I think it is much faster if I just create the layout class as trying to explain how it is done...

Bigsby:
Michael Sync's proposal is great

Chris is the one who created this textbox. I like his idea and his sample. So, I'm trying to spread this helpful information with everybody.

Bigsby:
ut the Portuguese keyboard works a little different.

Yes. Portuguese keyboard won't be like German Keyboard. So, you probably need to create your own keyboard for that. It's just key-mapping for your font so it might be not so difficult to create one. Chris might write about how to create our custom keyboard in my blog too.

Shall we just wait for the Silverligth 2 Final version??

Yes. it's the best option. Silverlight 2 final version or Silverlight 3 will definitely be better than Silverlight 2 beta. but sometimes, we can't just wait. so, we are sharing this workaround that we can use before we got some cool from MS.

This is not going well.

Michael Sync's proposal is great but the Portuguese keyboard works a little different. As I said before, there isn't a single key for the accented characters, for instance:

In the German keyboard PlatformKeyCode 187 resolve the 'ü';

In the Portuguese keyboard, to write a 'ã', you need to press PlatformKeyCode 191 where lies '~' (nothing happening in text at this time) and then press 'A' Key.

I tried to listenning to the KeyDown event and act according to 191 PlatformKeyCode and display the character but setting the TextBox.Selected property clears all text and displays only the text set for the SelectedText property.

Shall we just wait for the Silverligth 2 Final version??

Same here with Silverlight 2 and Portuguese (Portugal) keyboard.

When pressging '~' the TextBox writes '~~' instead of waiting for the next character and write the correspondend accented character like 'ã'.

As sad before, the AltGr key doesn't work, therefore making it impossible to write the character '{', '[', ']', '}', '€', '@' and '£'.

I wonder if this is supposed to be a bug or a feature because I had to developed a TextBox form scratch in WPF listening to SYS_CHAR to make something like the Mac TextBox that writes the accented in the selection when it is pressed.

I would love this to be a feature if the pressed character and not KeyboardEventArgs.Key (because the same KeyboardEventArgs have different characters deppending on the Keyboard Layout) was written and I could display the text I want no matter the Keyboard Layout used. Minding all keys and modifiers work.

Chris created one extended textbox for resolving this issue. Could you guys please test this textbox? http://michaelsync.net/2008/04/07/silverlight-2-beta1-international-non-us-textbox

Silverlight is great!

I'm having the same problem too. It's very serious bug...

Hope that the silverlight team correct it quickly!

I hope that you guys understand the severity of this bug. Without Alt-Gr support users will not be able to enter email adresses in german speaking countries (100mil population) as @ is mapped to Alt-Gr + Q. So please put this on the top of the list for bug fixes.

Ah yes, I'm seeing it. I was copying from the character map the first time, which does work, but I added the Spanish (Int'l Sort) keyboard and it looks like using the Ctrl+', <letter> input doesn't work. It also looks like if you just type ' or " into a textbox it inputs twice. Thanks for pointing the issue out.
