Hi @timunie I'm getting a binding error in NumericUpDown.Value when the bound property type is nullable decimal,
Nullable`1 Failed to convert value '<null>' (type '<null>') to the target type using converter 'SystemConvertConverter'. The fallback value will be used if it's available. InvalidCastException:'System.InvalidCastException: Null object cannot be converted to a value type.
Is it possible to configure NumericUpDown so that it doesn't complain?
decimalisn't supported correct. So be careful.
TargetNullValue=''in the binding
ControlTemplate. So if you create your own Syle you may add
Watermarkto any control, but unfortunately there is no generic way to do it. This is a limitation of WPF, not MahApps
