Object coding - returning UI Objects

[Badgers]

Hi,

I have a object data access layer which I use to return data via a datareader / dataset. I'm think of creating a Business Logic Layer, to actually return UI components instead.

For eg; Instead a calling a DAL layer 3 times and writing the code to build a dropdown box, why not call a BLL function which does the data access and return the dropdown already populated.

Is there much overhead with doing this in .net - is it okay as stuff is byref by default ?

Thanks inadvance.

Why dont you just bind the ddl to the datareader or dataset, and let the .net framework do the hardwork for you?

To answer your question though, the business layer should hanlde business logic. Creating a ddl is really a function of the presentation layer.

If you want to do it that way, have the Business layer return an arraylist or List<>, so that you can leave how hte data is presented to the top layer.

Just my $.02
