Ok I have this solved, I looped through the appointments and make them only span the current week, I create a new appointment for the next week with the remainder of the time on the appointment I split (and so on if the appointment spans multiple weeks).

This seemed to fix some of the display issues, the current month looked good, when back and looked at the previous month and it was still bugged. I looked through the appointment data again and noticed there were some same day appointments with a 0 duration, I updated those to have a one day duration and that cleaned up the rest of the display issues.

Please help this has been an ongoing issue for a while now. Its critical now. We can't show the screen to the client looking like this.

i can't seem to post the C# code without it pending approval

when i pasted my code in it says it requires moderator approval, it seems like the mods don't approve posts...
