Answer 1

You need to apply DesignerSerializationVisibility attribute to your property with DesignerSerializationVisibility.Content .

This tells the code generator to produces code for the contents of the object, rather than for the object itself. It helps in code generation for types other than primitive types.

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public List<int> SearchField { get { return _searchField ?? (_searchField = new List<int>()); } }
