Excluding the GroupBoxes that are inside another GroupBox

Question

Let's say I have 7 group boxes but some of them also have group box inside them and some do not. now if I want to iterate through those 7 group boxes and apply something to them, is there a way that I can exclude those Child group boxes from this loop?

Answer 1

Mark them with the tag property, or something.

Answer 2

though i question the choice of implementation (can you use polymorphism instead? what exactly are you trying to do?), there is a Parent property, e.g.

void soSomething(Control ctrl)
{
    if (ctrl is GroupBox && (ctrl.Parent is null || !(ctrl.Parent is GroupBox)))
    {
         //do something here
    }
    foreach(Control child in ctrl.Controls)
    {
        doSomething(child);
    }
}
