how to use .net controls in labview
The trouble with writing help files is that you have to settle on a target audience, and write for that. My feeling is that the section dealing with .NET in the LabVIEW help was written for someone who knows about .NET and just needs to know how to use it in LabVIEW. It's not intended to instruct someone on what .NET is and how to use it. So, someone looking for that will find it very limited. I, on the other hand, found it adequate, but that's because I've done .NET programming in C#. As for books, there is no book that deals exclusively in integrating .NET with LabVIEW, though I don't know if the latest editions of the more popular LabVIEW books have a chapter on this. I'm sure the authors will chime in with a plug if that's the case. 
As for examples, there are 5 examples that ship with LabVIEW that deal with .NET. The "NET Meetings Calendar" makes use of an actual .NET control on the front panel. The others seem to use constructors in code.
Using .NET in LabVIEW isn't really that much different than using ActiveX, so the same concepts apply. Also, using a .NET control in LabVIEW is very similar to using a .NET control in another programming language, such as C# or VB.NET. Basically, to use a .NET control you place a .NET container on the front panel and select the contol you want to insert into the container. That provides a reference to the control and you can set its properties and call its methods. Beyond that, it's a matter of the control as to how to program it.
Was there a specific control you wanted to know about?

You actually want the "Items" property and then that collections "Add" method, as shown below:
Tip: You should download the .NET help file, which is available with the .NET Software Development Kit. The help file contains all the documentation on all the .NET classes as well as tons of examples. There's also lots of web pages dealing with .NET controls.

Maybe you want to preselect one of the items as well....
Please note that this approach (just as the one from smercurio) is all the same for many .NET controls, just like smercurio already stated 🙂
hope this helps,
