Event from List RP

[soa]

I have a Form RP which contains a PRIM_LIST. In the PRIM_LIST one of the columns is a Prim_list.IListCellDesign RP. In the Cell I want to signal an event back back to the form but I don't know how to define the event in the Form RP as it would be coming from the PRIM_LIST but is not listed as an event on this object. Is this doable?

You can only handle an event on an object to which you have a reference.

So, for list processing, the simple solution to this is to grab a reference to the object when focus changes

Add a define_Com for the class of the reusable part and set it when ever the list focus changes. You'll then have a reference to listen to events on.

Code: Select all

Define_Com Class(#MyReusablePart) Name(#CurrentPart) Reference(*Dynamic)

Evtroutine #List.ItemGotFocus
#CurrentPart <= #PartColumn.Currentitem.Part *as #MyReusablePart
Endroutine

Evtroutine #CurrentPart.Something

Endroutine

Thank you. That worked and filled another little gap in my understanding (don't worry plenty left).
