c# mouseclick show which radiobuttons are checked

Question

I'm sure this is something simple.

I have a form with about a dozen plus Radio Buttons, all in the same group. I am trying to capture the name of the radio button that is selected if you click anywhere on the form. 

        private void MouseClick(object sender, MouseEventArgs e)
        {
               RadioButton btn = sender as RadioButton;
               Messbox.Show(//Selected button);
               
        }

I've tried using a switch statement but I am getting an error.

Any suggestions would be greatly appreciated 

Answer 1

Loop through all the radioButtons and check if Checked property is true:

StringBuilder sb = new StringBuilder();
foreach(RadioButton rb in groupBox1.Controls.OfType<RadioButton>())
{
    if(rb.Checked)
    {
        //if selected, add the name of radioButton tostringbuilder
        sb.AppendLine(rb.Name);
    }
}
MessageBox.Show("Selected RadioButtons are:\r\n"+ sb.ToString());

this.groupBox1.MouseClick += new System.Windows.Forms.MouseEventHandler(this.button1_Click);
