Good day!
I've faced one small problem conserning user controls: I've tried to create
an expanding (dropdown) panel inheriting from System.Windows.Forms.Panel base
class to allow developers drag'n'drop controls into my panel in design mode,
but accidently I've mentioned that the control seems to "eat" controls I drag
into its Controls Collection completely removing them from
InitializeComponent() function.
Maybe, there is any other way to create a control like this, without
inhereting from Panel?
