If you are using a SfGrid with remote data (e.g. WebApiAdapor) DataManager AND Offline=true (!) than filtering of complex properties is not possible anymore. The complex property will be still displayed and can be sorted but if you change the column filter nothing will be displayed anymore.



After try filtering "Übergeordnet" it´s empty and an OnFailure event will be raised:
With Offline=false or while using an explicit DataSource it works!
