How to set FallbackValue in binding as path to external image file?

Question

I\'m trying to set FallbackValue in case when my converter cannot be call, but I\'m not sure how to do that.

Answer 1

For the Image control, when you Binding the Source property with a URI string, it will automatically convert the URI to a BitmapImage. But if you set the FallbackValue and TargetNullValue as URI string, it will not display.

You need to set it as BitmapImage:

As we set the FallbackValue and the TargetNullValue as StaticResource of BitmapImage, It works.
