Custom Designer for a Control
I've got a custom class which derives from SplitContainer: namespace Builder.Components { public partial class ProjectSidebar : SplitContainer { public ProjectSidebar() { InitializeComponent(); } } } Now when I right-click and select View Designer I'd like to see the SplitContainer and edit it, like I would with the default controls (drop a panel in it, etc.). All I see is a message to add controls and switch to Code view . How to achieve this?
