The specified key did not exist in the directory

Hello, Robin. I have a problem when im trying to add some content on darkdockpanel.

darkDockPanel1.AddContent(new DarkDockContent());

The specified key did not exist in the directory.

DarkDockContent has to have either the DockArea or the DefaultDockArea property set.

Not really sure what the use-case is for creating content without any... well, content. Generally I create a custom user control that inherits from DarkDockContent.

In any case, you can do it by setting the DefaultDockArea in the initialisation of the object. In your case, it would look like this (change the dock area to whatever you want it to be):

darkDockPanel1.AddContent(new DarkDockContent { DefaultDockArea = DarkDockArea.Document });
