QuestionOwner drawn TabControl doesn't act as I want it Pin
WebMaster17-Oct-09 0:20

Hey guys.

So, my owner drawn TabControl, inheriting from the TabControl in System.Windows.Forms, doesn't want to give me a transparent background. (Or I simply don't know how) It's also giving me these weird gaps, and somehow it's not filling out all the space in my Panel parent.

Here's a screenshot: http://tinypic.com/r/1tou9h/4
