Question

I have multiple panels and on each panel I have 2 RadioButtons. I need a way to check if a radiobutton has not been selected within each panel. If the panel contains 2 radiobuttons during a loop and if those 2 radiobuttons are not selected the variable (submit) would then be set to false.

Here is my code so far –

        foreach(Panel panels in groupBox2.Controls)
        {
            foreach (RadioButton radio in panels.Controls)
            {
                if (!radio.Checked)
                {
                    submit = false;
                }
            }
        }

By default each panel will only contain one radio checked it the radio buttons AutoCheck is true, Anyway to your question:

foreach(Control parent in groupBox2.Controls)
{
    Panel panel = parent as Panel;
    if (panel != null)
    {
        foreach (Control child in panel.Controls)
        {
            RadioBox radio = child as RadioBox;
            if (radio != null)
            {
                if (!radio.Checked)
                {
                    MessageBox.Show(radio.ToString());
                    break;//if AutoCheck of all radio buttons seted to true
                }
            }
        }
    }
}
