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" /> 
                        <Key KeyType="Normal" Width="1" Height="1" VirtualKey="69" />

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: The Header setting of RadVirtualKeyboardWindow doesn't work when the window is opened on an environment requiring automation peers

The Header property setting is replaced with a default value when the RadVirtualKeyboardWindowAutomationPeer is created. This happens on environments where the automation peers creation kicks-in. Like, on touch devices, when a screen narrator application is used, on visual elements inspection with some tools (like UISpy or Snoop) or any other automation testing that requires automation peers. 

In that case, instead of the user defined Header value, the window's header is replaced with "RadVirtualKeyboardWindow" string.

To work this around, disable the automation peers:

public partial class App : Application 
{ 
    public App() 
    { 
        AutomationManager.AutomationMode = AutomationMode.Disabled; 
        this.InitializeComponent(); 
    } 
}

VirtualKeyboard: Diacritics characters are duplicated on the wrong key buttons
Some keyboards and OS settings (like AZERTY + French culture) support diacritic symbols. RadVirtualKeyboard doesn't display these properly. Some of the diacritics are duplicated on the key adjacent to the original key.

VirtualKeyboard: The Alt key is not toggled in the UI when the physical Alt is pressed
Pressing keys on the physical keyboard highlights the corresponding button in the VirtualKeyboard control. For example, if you press Ctrl, you will see that the Ctrl button in the UI will change its background while the key is pressed. This doesn't work for the Alt key. The button in the UI doesn't get highlighted.

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.

Key buttons are not correctly rendered (wrong width)

Key buttons are not correctly rendered (wrong width)

Our company would like to use in a greenfield project this new UI component.

On our machine, in both our sample projects and even running your official WPF Demo App, the virtualkeyboard component does not render its buttons correctly.

 

This is our sample xaml:

 

<Window x:Class="TelerikWpfApp1.MainWindow"
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                Title="MainWindow" Height="350" Width="525">
        <Grid>
        <telerik:RadVirtualKeyboard DefaultKeyboardLayout="Compact" HorizontalAlignment="Stretch" />
    </Grid>
</Window>

 

In the attachment you can see how the virtualkeyboard renders ootb. Are we missing something?
