A WPF text box control that behaves better when bound to a floating point property
(either Single or Double) and the binding defines a StringFormat.
On my first WPF project, I noticed a lot of challenges users had entering
floating point numbers into the standard TextBox control. So we developed a
subclass that manages the behavior better. See Article-FloatingPointTextBox.pdf
for more information.
If you are pulling this control into your own project, make sure you also grab
the extension method (string.HasOnlyOne(char)) defined in ExtensionMethods.cs.
In the Main directory is a small Example program that uses both a TextBox and
a FloatingPointTextBox control so you can examine the differences in their
behavior.
If you change the StringFormat on one of these controls' bindings in MainWindow.xaml,
be sure to change the other one to the same value.
