Hi,


  1. Create a dbView
  2. Create a RadioGroup
  3. Create a Property inside the RadioGroup

Ok, you will have something like this:

Code:
Use Windows.pkg
Use DFClient.pkg

Deferred_View Activate_oBugVDF for ;
Object oBugVDF is a dbView

    Set Border_Style to Border_Thick
    Set Size to 200 300
    Set Location to 2 2

    Object oRadioGroup1 is a RadioGroup
        Set Location to 47 86
        Set Size to 54 77
        Set Label to 'oRadioGroup1'
        
        Property Boolean pbHelloWorld True
        
        Object oRadio1 is a Radio
            Set Label to "Radio Label 1"
            Set Size to 10 61
            Set Location to 10 5
        End_Object
    
        Object oRadio2 is a Radio
            Set Label to "Radio Label 2"
            Set Size to 10 61
            Set Location to 25 5
        End_Object
    
        Object oRadio3 is a Radio
            Set Label to "Radio Label 3"
            Set Size to 10 61
            Set Location to 40 5
        End_Object
    
        Procedure Notify_Select_State Integer iToItem Integer iFromItem
            Forward Send Notify_Select_State iToItem iFromItem
            //for augmentation
        End_Procedure
    
        //If you set Current_Radio, you must set it AFTER the
        //radio objects have been created AND AFTER Notify_Select_State has been
        //created. i.e. Set in bottom-code of object at the end!!
    
        //Set Current_Radio To 0
    
    End_Object

Cd_End_Object
At the "Code Explorer" panel select the RadioGroup, go to "Properties -> Events" panel and double click over the event "OnRadioGroupEntering".

The result is:
Code:
        Function pbHelloWorld Returns Boolean
            Boolean bRetVal
            Forward Get pbHelloWorld to bRetVal
            
            Function_Return bRetVal
        End_Function
I notice this behaviour in 16.0, 15.1 and 15.0 with many other controls and many other events, you can try for example a "ComboForm" with "OnChildWrapping".

Regards.
