Thanks I already looked at that sample but our use case is that we need to show all three characters.

Hi,
I was trying to use the suggestion you gave about accessing the CapitalCase property, but I am not able to find any sample of how to access that from my color converter.

Code
Select All
<TextBlock Text="{Binding UpperCase}" Foreground="{Binding UpperCase, Converter={StaticResource UpperCaseColorConverter}}"/> 



I have similar converter's defined for Lower and Alter case as well.


Thanks,
Harshvir

Hi,

Try binding to the Key instance instead of its UpperCase specifically, then you should have access to all Key's properties in the value converter.

Hi,
I think I am not able to explain my problem clearly.
I have attached keyboard image and circled few keys which are showing problem.
Keyboard language used is French.
Key in Red, is highlighting both characters.
Key in Green, is highlighting none characters.
Key in blue is highlighting lower case, but sending upper case key. This happen only when Caps lock is enabled.

I have issues with Random keys on different languages.
I have used combination of shifts and caps.
Checking for char.isLetter and IsEffectedByCapsLock (Code Below).

Code
Select All
        private bool IsEffectedByCapsLock(string data, bool isLetter)
        {
            if (Regex.IsMatch(data, @"\p{IsCyrillic}"))
            {
                return true;
            }
            else if (isLetter && Regex.IsMatch(data, @"\p{IsGreek}"))
            {
                return true;
            }
            else if (isLetter && (Regex.IsMatch(data, @"\p{IsBasicLatin}", RegexOptions.None) || Regex.IsMatch(data, @"\p{IsLatin-1Supplement}", RegexOptions.None)))
            {
                return true;
            }
            return false;
        } 



The issue do not happen for English language, but for non-english languages.

Please attach a test project (here or with PM) containing your converter code and templates.

You can get the key instance itself using multi-binding, keeping CurrentCase property binding to trigger updates. E.g. this highlights / unhighlights the French μ in my test:

Code
Select All
<TextBlock Text="{Binding UpperCase}">
    <TextBlock.Foreground>
        <MultiBinding Converter="{StaticResource TestUppercaseConverter}" >
            <Binding Path="." />
            <Binding Path="CurrentCase" />
        </MultiBinding>
    </TextBlock.Foreground>
</TextBlock>

public class TestUppercaseConverter : IMultiValueConverter
{
    public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
    {
        var key = values[0] as RegularKey;
        if (key != null && key.UpperCase == key.CurrentCase)
            return OSKKeyTextColors.Highlighted;
        return OSKKeyTextColors.Dimmed;
    }

    object[] IMultiValueConverter.ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
} 



Other converters should be equivalent, or maybe you could pass which property to compare with CurrentCase as converter parameter instead of using multiple classes.

Slavcho

Thanks Slavcho.
That was what I needed, and it's working as expected for me now but for special keys only.
For Text Keys (when both Caps and Shift are on), its highlighting capital case, and sending lower case.

Please check with both Caps and Shift on. When we use the method provided, then it messes up some other keys.
Here is an example for French Keyboard.
I added the following log statement to both Upper and Lower case converters.
Code
Select All
Debug.WriteLine("UpperCaseColorConverter -- " + "Uppercase: " + key.UpperCase + ", CurrentCase: " + key.CurrentCase + ", LowerCase: " + key.LowerCase + " -- Value From key: " + values[1]);
 



Here is the output.
Code
Select All
UpperCaseColorConverter -- Uppercase: §, CurrentCase: §, LowerCase: ! -- Value From key: §
LowerCaseColorConverter -- Uppercase: §, CurrentCase: §, LowerCase: ! -- Value From key: § 



You can see that in both Upper and Lower case values. I get same CurrentCase value along with the value[1] which is mapped to CurrentCase.
But what it types in UI, is !.

Here CurrentCase should reflect combined Caps + Shift:

Thanks for sharing the DLLs, do you know what is your next release cycle, so we can get the tested Control/DLL, rather than temporary file share?

We have released this with a small update here we were just preparing for another client -
https://mindfusion.eu/Forum/YaBB.pl?num=1600942278/0#0

Shift + Caps seems to work nice with CurrentCase-based converters, we've tested English and French so far.

Thanks Slavcho. It's good to know that there are no untested changes.
