Question

I have a WinForms dialog box that contains 3 radio buttons. I am using ApplicationSettings to bind the Checked property of each of these RadioButton controls, but it doesn’t do what I am expecting it to do. Now I have to click each radio button twice before it gets checked and the selected radio button is not being persisted.

Is there a line of code I need to execute when the form is closed that saves the user settings?

How do I eliminate the need for 2x clicking on the radio buttons?

Is there a better way to persist this type of user setting? I do have a public property on the dialog box class that gets/sets an enum value based on which radio button is checked, but I didn’t see an easy way of binding that property to a user setting.

Edit: Should have specified that I’m using vb.net. I think that means My.Settings instead of Properties.Settings.

I can answer this part of your question:

Is there a line of code I need to execute when the form is closed that saves the user settings?

Application settings are stored in your Settings class, in the Properties namespace. The Settings class has a static property called Default, which represents the current settings for your application. So in your main form’s Closing event, you call:

Properties.Settings.Default.Save();

… to save the settings.

Likewise you can get to the settings programatically using the setting’s name: Properties.Settings.Default.MyRadioButtonState (or whatever you’ve called it).
