I have a grid with note types and note subtypes where the ID's for the note subtypes are not unique across all note types, just for the note type they are related to. Each NoteTpye object has a NoteSubTypes collection property.
Basically they work like below [id]-[value]
1-NoteType1
1-NoteSubType11
2-NoteSubType12
2-NoteType1
1-NoteSubType21
2-NoteSubType22
Because of this when I need to bind the items source of the NoteSubType column to NoteType columns selected NoteType.NoteSubTypes property. Here's what I have so far:
I just need to get the NoteSubType ItemSource. I have a IValueConverter and IMultiConverter already created for this if we need them (from experimentations with other grids).

Hello Jeremy,

I would recommend you to use an ItemSourceBinding for the second column. You may take a look at this blog post for further reference.
Let me know in case you need any further assistance.

That works, but it does mean putting the lookup for the list that is used for display in a dataobject that is not concerned with display at all. Not really ideal.
Is there a way to reference the value of one column from the binding another?
