如何在文本框中完整文件掩码

Question

我正在使用infragistics控件进行屏蔽输入。我为XamMaskedInput创建了自己的IP地址和固有类的掩码输入。

继承的类看起来像：

   public class IpMaskedTextBox : XamMaskedInput
    {
        BrushConverter bc = new BrushConverter();
        public IpMaskedTextBox() : base()
        {
            Background = (Brush) bc.ConvertFrom("#F0FAFF");
            BorderThickness = new Thickness(0);
            BorderBrush = null;
            Padding = new Thickness(5,0,5,0);
            FontWeight = FontWeights.Bold;
            VerticalContentAlignment = VerticalAlignment.Center;
            HorizontalContentAlignment = HorizontalAlignment.Center;
        }

        // Prevent space character
        protected override void OnPreviewKeyDown(System.Windows.Input.KeyEventArgs e)
        {
            base.OnPreviewKeyDown(e);

            switch (e.Key)
            {
                case Key.Right:
                    e.Handled = true;
                    break;
                case Key.Left:
                    e.Handled = true;
                    break;
            }
        }
    }

和xaml上的外观：

我的问题是，如何从文本框中完整填充整个范围的提示字符，左边和右边没有空格。

结果应该是这样的：

最后我找到了风格：
