WPF：{：F2 0}文本框用的StringFormat = {}绑定。不显示为零的

我的对象绑定到一个文本框与下面的XAML代码：

I am binding an object to a TextBox with the following XAML:

＆LT;文本框名称=MyTextBox文本={绑定路径= myvalue的，模式=双向，的StringFormat = {} {0：F2}}/＆GT;

当然，当我绑定一个新的对象（值都仍为零）的Text属性设置为 0.00 。我有几个这样的文本框，这使得它繁琐进入一个新的前删除的每个值。

Naturally when I bind a new object (which values are all still zero) the Text property is set to 0.00. I have several of these TextBoxes, which makes it tedious to delete every value before entering a new one.

目前我使用的 Window_Loaded 方法，这些盒子的那一刻href=\"http://stackoverflow.com/questions/974598/find-all-controls-in-wpf-window-by-type\">FindVisualChildren方法。

At the moment I'm clearing these boxes in the Window_Loaded method using the FindVisualChildren method.

我就觉得笨重，但。是否有这样做的一个非常简洁的方式？

It just feels clunky though. Is there a neat way of doing this?
