Variable layout

Hello,

I have a combobox with an eventhandler attached to it. I want to show a
variable number of labels/buttons in the form depending on the item which is
selected from the combobox. My first thought was to create a tabcontrol with
hidden tappages and select the appropriate tab. Unfortunatly it's impossible
to hide tappages. Now i'm thinking of creating panels and show/hide them on
a selection change. Drawback of the approach is that i can't use the
graphical form designer of Visual Studio (position panels etc.). Any better
solutions to this problem? Thanks in advance!

Greetings Eric
