A WPF TextBox for entering a currency value, similar to how a cash register works.

• Numbers typed are pushed in from the right. If we start with the default value 0.00, and start typing the numbers 123, the value updates as such: 0.00 => 0.01 => 0.12 => 1.23
• If we press the backspace key, the numbers are shifted right: 1.23 => 0.12 => 0.01 => 0.00
• If we press the delete key, the value is reset to 0.00.
• If we press the minus key, the value becomes negative.
• Copy and paste are disabled (both via context menu and keyboard shortcuts)
• This control's template can be customized to change the appearance.
• Supports data validation.

Add a reference to CurrencyTextBoxControl.dll from your project, then add the following namespace to your XAML:

xmlns:currency="clr-namespace:CurrencyTextBoxControl;assembly=CurrencyTextBoxControl"

Insert the control like this:

<currency:CurrencyTextBox Number="{Binding Number}" />
