XamDataGrid

390

Jeremy posted over 14 years ago

I have a xamDataGrid bound to an ObservableCollection<Note>. Among other things the Note objects have properties for NoteTypeID and NoteSubTypeID.

I also have a ReadOnlyCollection<NoteType>. Each NoteType object exposes its ID and Name as well as a ReadOnlyCollection<NoteSubType>. Each NoteType object has a unique list of NoteSubTypes (but the NoteSubTypeID's aren't unique).

I've bound the NoteTypeID to a XamComboEditor and that column is displaying correctly. What I'm having trouble with is binding the second XamComboEditor. I need to set the ItemsSource property to the NoteType XamComboEditor's SelectedItem.SubTypes.

I have this working outside of the grid, but can't seem to get it working within the grid. Hints?

Hello,

If it is working outside the XamDataGrid, you should be able to make it run inside as well. I am a little lost with Note, NoteType, NoteTypeID and NoteSubType, but if you provide us with a sample of your structure and what you are trying to achieve, then we can definitely take a look at it.

Thanks!

Is this even possible? Or is the grid going to try to use the same ItemsSource for the combobox in each row?
