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?
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);
}
}
