After putting a pane in a group of tabs (UltraDocManager), and setting the TabLocation = Left, where in the designer can I rotate the text to make it horizontal? I can do this with UltraTab, so I assume I can do it with docked panes too.
It looks like this is not customizable on the dock manager. I would recommend submitting a feature request for this: http://devcenter.infragistics.com/Protected/RequestFeature.aspx.
I was able to do this using a template, see
