data binding - Databound WPF CheckBox eating exceptions on value set -


I have a database WPF checkbox control, which appears in the exception field thrown by that property setter when toggle the value The UI is done I know this may be if I provide an exception validation rule on the compulsory example, but I double-checked that the validation rule for the binding example is treated as zero. I also examined the call stack to interfere with exception handlers and none was present. However, the thrown exception is not bubble at the top and causes an accident in the app as I expected.

If I throw an exception to a button click handler in the same UI, the exception bubble is up

Any ideas?

Thank you!
