VirtualKeyboard: Add an option to prevent the change of the OS keyboard layout when setting the Culture property

Currently, when setting the Culture property of the RadVirtualKeyboard control, the OS keyboard layout will be changed as well.

We can add an option to control this behavior.

VirtualKeyboard: Add a default button style property that allows you to style the key buttons

Add a property that allows you to set a Style targeting the key button elements. The property should work in the default scenario where the RadVirtualKeyboard control uses its default VirtualKeyboardTemplateSelector. If the selector is replaced, thus the DataTemplates with the buttons, the new property should not be applied.

VirtualKeyboard EmptySpace breaks layout

Hello,

I found a bug where the EmptySpace element breaks the layout. When I use a Key-Button instead, the layout shifts to the correct position. However, I don't actually want to have any button in this position at all.

EmptySpace Element:

<RadVirtualKeyboard xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <Grid> 
        <KeysLayout KeySpacing="0.1"> 
            <Rows> 
                <Row> 
                    <Keys>
                        <Key KeyType="Normal" Width="1" Height="1" VirtualKey="81" /> 
                        <Key KeyType="Normal" Width="1" Height="1" VirtualKey="87" />

VirtualKeyboard: CapsLock key toggles the secondary display text of non-letter keys

VirtualKeyboard: CapsLock key toggles the secondary display text of non-letter keys

The CapsLock key should toggle only the letters. Currently, it behaves as Shift because it shows the secondary text of other keys as well (for example the number keys and their special characters). To reproduce this the ShowSecondaryText attribute of the corresponding key should be set to False.

To work this around, you can create a custom view model for the numeric keys that updates the DisplayText manually.

public class CustomKeyFactory : DefaultKeyFactory
{
    public override BaseKeyViewModel CreateKey(int virtualKey, KeyType keyType = KeyType.Normal, string displayText = null, double width = 1, double height = 1, int alternateVirtualKey = -1, string alternateText = null, bool showSecondaryText = false)
    {
        if (keyType == KeyType.Normal)
        {
            return new CustomRegularKeyViewModel(virtualKey, width, height, showSecondaryText, displayText);
        }
        return base.CreateKey(virtualKey, keyType, displayText, width, height, alternateVirtualKey, alternateText, showSecondaryText);
    }
}

public class CustomRegularKeyViewModel : RegularKeyViewModel
{
    public CustomRegularKeyViewModel(int virtualKey, double keyWidth, double keyHeight, bool showSecondaryText, string displayText = null) : base(virtualKey, keyWidth, keyHeight, showSecondaryText, displayText)
    {
    }

    public override void Update(IKeyUpdateContext context)
    {            
        base.Update(context);
        if (this.VirtualKey >= 48 && this.VirtualKey <= 57) // you may need to extend the if-statement to check for other keys as well
        {
            this.DisplayText = context.IsShiftActive ? this.ShiftText : this.LowerText;
        }
    }
}

VirtualKeyboard: AltGr key is not working as intended on cultures that use it as a special keys modifier

VirtualKeyboard: AltGr key is not working as intended on cultures that use it as a special keys modifier

On English keyboard the AltGr key is treated as Right Alt key which behaves the same as the standard (Left) Alt key. However, on some cultures (like French) the AltGr key is used as a modifier that toggles few special keys. This behavior is similar to holding the Shift key, but the set of special keys that are activated is different.

Currently, RadVirtualKeyboard doesn't support the special behavior of the AltGr key.
