Keep in Mind that modes are played in a certain key just starting with a different note... So when you move from C to D, you are not changing keys, 2nd tone in the key is being emphasized.
So in our example there is no D- Ionian. Playing D in the Ionian mode would give you a different set of notes and change the song.
Each mode makes a pattern on the fretboard, I haven't committed them all to memory so we are more than likely in the same boat...
http://www.wheatdesign.com/bassbook/chapter_select.php?chapter=010 has all the modes in a diagram commit the diagram to memory. You want to eventually be at the place where you can
just play without thinking.
I relate it to me learning how to type, I took typing in 7th grade and almost failed, although I knew exactly how to read and right, and speak for that matter, but over time as I familiarized myself with different patterns on the keyboard, I can now type close to 70 words per minute. I type without even thinking about it really. So we learn all this stuff to essentially not to think about it.

I kind of take exception to modes are typically taught... First you are taught C Major scale, then you are told about all these modes that derive from the C major scale... It makes absolutely no sense to someone trying to learn how to make sense of how music works. Then you are told practice, practice, practice... I know one thing once I get a grasp of how all this theory works... I am gonna sit down and revamp, the way theory is taught and right a book.
