.NET 4.0 RadioButtons binded to a bool. Does it work?

Apr 21, 2011 at 2:54 PM
My understanding is that the .NET 4.0 has fixed databinding of radiobuttons. This has been a sinkhole in terms of time. Can someone
please show me how to databind two radiobuttons to a bool using 4.0...I have tried so many different permutations (some work for awhile but eventually stop).
I have tried giving them different groupnames, but giving them the same BindingGroupName in the Binding statement...Doesn't fly...I would
really appeciate some help! Thanks!!!!
