Question

I have a listBox using an itemTemplate that contains the following line:

Answer 1

In BindingBase have two properties: TargetNullValue and FallbackValue.

TargetNullValue returns your value when the value of the source is null.

FallbackValue returns your value when the binding is unable to return a value.

Example of using:

    
    

    
    pack://application:,,,/NotFound.png

    
    pack://application:,,,/NullImage.png
