Changed ItemsSource of RadDataBoundListBox and got this crash. Actually got this crash many times. Every time when is set any size-related properteis it crashes.

version: 321 & 509 nightly build.


Also setting MaxHeight works as MinHeight... weird...

Hello,

Thanks for writing.

We are currently not aware of similar behavior. In order to be able to investigate the case we will need to debug it on our side and see what goes wrong. Can you please give us some further hints on how we can do this so that we make sure that we sort out any possible issues? It will be also great if you can send us a demo project that we can use to reproduce the case (you will need to open a new support ticket to do that).

As for the MinHeight/MaxHeight issue, normally these properties are handled by the Control itself, we do not have any special logic related to them but anyway: any further details on this are also appreciated.

Thanks for your time.

All the best,
Deyan
