If one check box is selected, check another box.

Question

I have two checkboxes in my form; chkBuriedand chkAboveGround. I want to configure it, so if one of them is checked, the other is not installed. How can i do this?

I tried the property CheckChanged:

private void chkBuried_CheckedChanged(object sender, EventArgs e)
{
    chkAboveGround.Checked = false;
}
private void chkAboveGround_CheckedChanged(object sender, EventArgs e)
{
    chkBuried.Checked = false;
}

And it works, just not as good as I hoped. That is, when I check chkBuried, then check chkAboveGroundboth boxes will not be checked before I can check another one again.

Answer 1

change your code as below.

private void chkBuried_CheckedChanged(object sender, EventArgs e)
{
    chkAboveGround.Checked = !chkBuried.Checked;
}
private void chkAboveGround_CheckedChanged(object sender, EventArgs e)
{
    chkBuried.Checked = !chkAboveGround.Checked;
}

Answer 2

I suggest you use check_click instead of check_changed

        private void checkBox1_Click(object sender, EventArgs e)
        {
            checkBox2.Checked = false;
            checkBox3.Checked = false;
        }

        private void checkBox2_Click(object sender, EventArgs e)
        {
            checkBox1.Checked = false;
            checkBox3.Checked = false;
        }

        private void checkBox3_Click(object sender, EventArgs e)
        {
            checkBox1.Checked = false;
            checkBox2.Checked = false;
        }

List<CheckBox> groupOfCheckBoxes = new List<CheckBox>();

This will work for two unverified mailboxes, since they are already removed, it’s easier.
I had to do it myself.

private void customer_IsCheckedChanged(object sender, EventArgs e)
{
    business.IsChecked = false;
}

private void business_IsCheckedChanged(object sender, EventArgs e)
{
    customer.IsChecked = false;
}
