Best way to databind a group of radiobuttons in WinForms

Question

I\'m currently working on databinding some of my existing Windows Forms, and I\'ve ran into an issue figuring out the proper way of databinding a group of radiobutton contro

Answer 1

Set the tag name of your radio buttons to something that represents the value.

Create a string setting, for example, OptionDuplicateFiles, and give it the default value of the tag name for your default radio button.

To save your checked radio button:

Settings.Default.OptionDuplicateFiles = gbxDuplicateFiles.Controls
   .OfType()
   .Where(b => b.Checked)
   .Select(b => b.Tag)
   .First()
   .ToString();

To load your checked radio button:

(gbxDuplicateFiles.Controls
   .OfType()
   .Where(b => b.Tag.ToString() == Settings.Default.OptionDuplicateFiles)
   .First())
   .Checked = true;

Tada!
