How do I get which radio button is checked from a groupbox?

Question

I have these groupboxes:

I want to run some code according to checked true state of a radio button like:

string chk = radiobutton.nme; // Name of radio button whose checked is true switch(chk) {     case "Option1":         // Some code         break;      case "Option2":         // Some code         break;      case "Option3":         // Some code         break; } 

Is there any direct way so that I can only get the name of the checked radio button?

Answer 1

You can find all checked RadioButtons like

var buttons = this.Controls.OfType<RadioButton>()                            .FirstOrDefault(n => n.Checked); 

Also take a look at CheckedChanged event.

Occurs when the value of the Checked property changes.
