Checkbox is a control that allow user to get boolean values from user for a spesific question like "Are you ok?".
Has a event called CheckedChanged, which occurs whenever the check property is changed.
Here is a CheckBox that has a question "Is Checked?".
We got this MessageBox from CheckedChanged event,
private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
bool IsChecked = checkBox1.Checked;
MessageBox.Show(IsChecked.ToString());
}
If CheckBox is checked -> IsChecked variable will be true.
If CheckBox is not checked -> IsChecked variable will be false.
