Summary0005665: TJvDBLookupCombo and TJvDBComboBox not simmetrical features
I really love JVCL and some components especially!
But, I hit 2 different faults at 2 alike components:
At first TJvDBLookupCombo there are very useful function "EmptyValue" that make possible to easy clear key value by user.
At second TJvDBComboBox there are particularly useful function "ListSettings->Filter" that make possible to use for many TJvDBComboBox just one Dataset/Datasource with individual filtering!
But I as many developments need both of those functions - EmptyValue and ListFilter!
Please, add EmptyValue function to TJvDBComboBox ListSettings as fast as possible!
With best regards!

Also you can see, that only JV DBComboBox does not have property to setup Key for Clear Value! For example: TDBLookupComboBox have property NullValueKey where developer can set any keyboard key or keys combination to fast clear value; also TcxDBComboBox and JvDBLookupComboEdit have the same property ClearKey; etc.
For now JvDBComboBox does not have NOTHING to easy clear value by user!

Excuse, but I just start learning Delphi, and I dont know how use "diff files" so I can not make a big help with resolving this problems.
JVCL already have all 3 function that I talking about but separately at different components!
I just ask to consolidate all 3 functions (Filter Lookup/List, EmptyValue, ClearKey) first of all at JvComboBox and maybe at all other Lookup components like - JvDBLookupCombo, etc..
You just need to copy those function from one to other component... it's must be very easy for professional...

No, it's not easy and fast, it needs to be done in a logical way, and copy/paste is not the best choice.
Someone with DB knowledge will have to look at this.
