I´m creating a game with my own UI and its controls/components. Currently I have some problems with the event handling. Let me tell me the way I do it right now. Every object is handles as a component (also the form itself). Each component can implement an interface with a container which can contain a list of components (and so on and so on). An example: I have a form. On this form there is a TabControl. In this TabControl there are different TabPages and in these pages there are buttons.

I now have to handle my events that when I click on the button, the overlaying controls should not fire an event (like OnClick etc.).

How can I easily do that? I have a current function which runs recursively but only on two levels depth or something.

Here is my current function which is not working as expected:

private Boolean HandleComponentList(IComponentList parent) { 
foreach (var singleItem in parent.Components.OrderByDescending(i => i.ID).Where(singleItem => singleItem.Visible))
{
    // Cast item to IComponentList.
    var castedList = singleItem as IComponentList;
    // If list is not null (so it implements IComponentList), call HandleComponentList for Components in this control first.
    if (castedList != null)
    {
        // If an event has been raised, break function.
        var eventFound = HandleComponentList(castedList);

        if (eventFound)
            return true;
    }

    // Only fire events if control is enabled.
    if (singleItem.Enabled)
    {
        // look for events.
    }
}

return false;

}

Would be great if someone has some suggestions! Thank you!
