Cannot bind empty textbox to nullable decimal with MVVM light

Question

Is there any solution to binding a textbox to a nullable decimal? Whenever you leave the textbox empty the binding is not updated. I know one solution is to use a string property instead but I really don't want to do it that way.

Answer 1

You can do the trick by using TargetNullValue.

<TextBox Text="{Binding Value, TargetNullValue=''}"/>
