Addnewrow doesn't show when child collection is empty

Darryl Roberson posted over 12 years ago

My child fieldlayout doesn't show the add row when the child collection is empty. Did I miss a setting? Thanks.

I was using ObservableCollection(T). Will change collection type. Thanks.

Hi,

Use a BindingList and make sure it is instantiated and not null.

I am attaching a sample.

The first person has its Cars collection set to null - no AddNewRow

The 2nd person has its cars collection instantiated and has not cars - AddNewRow Appears.

I am attaching a sample application that illustrates these points.

Sincerely,
