TDS overwrites existing model

Question

I am new to TDS. I have a template which has a ContentList field of type TreeList. This field is allowed to select any page template. When I map this changes in TDS(Visual Studio) the tds generates a model automatically for this field like,

object ContentList{get;set;} but I want this as IEnumerable(IMytmeplate) ContentList{get;set;}

Whenever I make changes in CMS and merge in code this is getting overwritten. Is there any way to achieve the desired result? Similarly I have a date picker field and I want it to be nullable. Whenever I make changes to content in CMS and merge in code these fields are getting overwritten and I need to make the changes manually.Any help would be appreciated. Thanks in advance

Answer 1

This functionality is available OTTB in TDS, to accomplish this you can follow below steps:

1. Select ContentList field item and right click and select Properties

2. Go to Custom Data field and type

type=IEnumerable<Namespace.IMytmeplate>

3. Again sync, it will work
