WPF Textbox accept INT but not NULLABLE INT?
c#, int, nullable, wpf
Solution
Use:
{Binding TargetNullValue=''}
Problem
Model ``` public int? SizeLength { get; set; } ``` XAML ``` <TextBox Text="{Binding [someViewModel].SizeLength, Mode=TwoWay}"></TextBox> ``` Once user try to backspace or delete the value in this `textbox`, a message `Value '' cannot be converted`. May I know what's wrong with it?
