Answer 1

Try this:

public class BooleanToVisibilityConverter : IValueConverter
{
    private object GetVisibility(object value)
    {
        if (!(value is bool))
            return Visibility.Collapsed;
        bool objValue = (bool)value;
        if (objValue)
        {
            return Visibility.Visible;
        }
        return Visibility.Collapsed;
    }
    public object Convert(object value, Type targetType, object parameter, string language)
    {
        return GetVisibility(value);
    }
    public object ConvertBack(object value, Type targetType, object parameter, string language)
    {
        throw new NotImplementedException();
    }
