Is there an attribute that can be set on a field so that it does not ever get downloaded to the client?

I have a field which is fairly large and used only for searching, so it doesn't need to get sent down to the client. I do need to be able to populate it on the server however.

Hi Greg,

There is. The attribute is called IgnoreDataMember ( http://msdn.microsoft.com/en-us/library/system.runtime.serialization.ignoredatamemberattribute.aspx - http://msdn.microsoft.com/en-us/library/system.runtime.serialization.ignoredatamemberattribute.aspx )

We also have a couple of suggestions that we recommend before going the attribute route.

1. You can create a subset of the entity, excluding the fields that you don't want to send to the client.

2. Or you can create a secondary entity with the excluded fields and create a 1 to 1 relation with the main entity. This is such that when you query for the main entity, you have an option to exclude that secondary entity.

Hope this helps.
