C# WinForms – Grouping Radio Buttons in Different Panels

.netc++radio-buttonwinforms

I'm using C# to develop WindowsForms application. I have created a form with some panels. Each panel has a RadioButton. When I click a RadioButton, and then other one, both are checked.

How could I simulate that all the RadioButtons are in the same group, so only one can be checked, and the others are unchecked?

Of course, I can control the checkedChanged event for each RadioButton … but is there any better solution?

Thanks in advance.

RadioButtons are automatically linked if they are inside the same parent. Since you want them to live in different containers you will have to link them manually.

Put all radio buttons for a group in a container object like a Panel or a GroupBox. That will automatically group them together in Windows Forms.

I'm afraid you'll have to handle this manually... It's not so bad actually, you can probably just store all the RadioButton in a list, and use a single event handler for all of them:

private List<RadioButton> _radioButtonGroup = new List<RadioButton>();
private void radioButton_CheckedChanged(object sender, EventArgs e)
{
    RadioButton rb = (RadioButton)sender;
    if (rb.Checked)
    {
        foreach(RadioButton other in _radioButtonGroup)
        {
            if (other == rb)
            {
                continue;
            }
            other.Checked = false;
        }
    }
}
