Question

Hey I just started working on Toggle Buttons and I have set the properties of the button. I want to check for the toggle state which should return me 1 or 0.

XAML:

<ToggleButton Grid.Column="3" Content="On" Command="{Binding VoltageToggleCommand}" IsChecked="{Binding Path=IsChecked}" Name="VoltageToggleBtn" />

ViewModel Class:

private ICommand mToggleButtonCommand;
    public ICommand VoltageToggleCommand
    {
        get
        {
            if (mToggleButtonCommand == null)
                mToggleButtonCommand = new DelegateCommand(new Action(ToggleButtonCommandExecuted), new Func<bool>(ToggleButtonCommandCanExecute));

            return mToggleButtonCommand;
        }
        set
        {
            mToggleButtonCommand = value;
        }
    }

    /// <summary>
    /// Check for ToggleButton State
    /// </summary>
    private bool isChecked;
    public bool IsChecked
    {
        get { return this.isChecked; }
        set
        {
            this.isChecked = value;
            this.OnPropertyChanged("IsChecked");
        }
    }

    public bool ToggleButtonCommandCanExecute()
    {
        return true;
    }

    public void ToggleButtonCommandExecuted()
    {
        Byte[] cmdArray = new Byte[256];
        int numBytes = 0;
        cmdArray[numBytes++] = // Here I wanna retrieve the toggle state i.e. 1 or 0
        // Some Code
    }

Thus when I click the toggle button, controls reaches ToggleButtonCommandExecuted() where I need to check for the state and store it in cmdArray. Basically when code is executed cmdArray[numBytes++] = 1 or 0.

How can I achieve it? 🙂

Answer 1

you will have to convert from boolean to byte yourself

cmdArray[numBytes++] = (byte)(IsChecked ? 1 : 0);
