Visual Studio 2008 - radiobutton databind

[ravno]

I have a problem binding a radiobuttongrou p to a dataset/datasetbindings ource.
I have a field - among many others - in the dataset, holding int values 1-6
All fields are shown in textboxes on the windows form.
But how do I make the radiobuttongrou p show the value of the int field.
value=2 => radiobutton2 is selected

Can annyone xplain ?

I have ran across an OptionGroup in Documentation. I think, that's what I've been looking for - but how do I get it into my ToolBox, so I can use it on a form ?
