UltraListView Items up-gradation from 6.3 to 9.2
posted

We have up-graded Infragistic 6.3 to 2009 v2. In old version we were using the logic of inserting the same key in exception handling. Whenever a new key is adding if that key already exists in the listview then an exception of already key exists occur. But after up-gradation with same code listview is adding a null value if same key is inserting and exception occur.

This is the strange behavior as our application is running from last 3 years and suddenly start throwing exception.

Is this a bug and modification in listview?

    Generally speaking we try to maintain legacy behavior with new versions, and (except in rare circumstances) when we fail to we consider it a regression bug.

    I just checked and the latest build of NA2009.2 throws a duplicate key exception as expected. The only circumstance under which it doesn't is when the key is null or empty, and this behavior is by design and has been in effect for as long as I can remember.

    If you like you can post a simple sample project here and we can take a look.
