In this video I introduce the RadioButton control for C# Windows Form Applications.
NOTE: There was an odd bug at the end of the video where I set the radioButton2 Checked property to true, but when my form application launched it showed radioButton1 as the default selection. In my Design view properties window, I toggled the radioButton1 Checked property to true, then back to false, and then reset radioButton2's Checked property back to true, and that fixed the issue. Not sure what was going on during the example!
