我比较习惯用样式去处理这些问题
添加一个TextBox
首先在鼠标没有任何动作的时候，希望如Label一样显示，我想将TextBox背景和边框置为无就可以了，至于鼠标操作的效果都去样式里设定。

添加各种控件事件来动态生成控件或绑定一些操作。

在TextBox 的 GotFocus 与 LostFocus 这两个事件结合
代码：
XAML:
<TextBox x:Name="txt" GotFocus="txt_GotFocus" LostFocus="txt_LostFocus"></TextBox>
CS:
private void txt_GotFocus(object sender, RoutedEventArgs e)
{
this.txt.Background = Brushes.Red;
}
private void txt_LostFocus(object sender, RoutedEventArgs e)
{
this.txt.Background = Brushes.Blue;
}
