I have inherited a frankenstein VB6 "Converted" to VB.NET winform application. This application has a metric ton of fields in it, the users rightfully complained that the tab order is off (after a certain point it starts jumping all over the form).
Figuring something in tab order was off, I went in and turned on View > Tab Order and it looked good.
To be sure I went through the form again fresh and when I'm in tab order view all is well, but when the app runs it still starts jumping around the same area as before?! Has anyone else encountered this and how did you resolve if you did?
[Edit]: These input forms are all on separate tabs within a tab control, which probably muddies the situation even more.
Are there any strange Focus calls in the code that are overriding the tab order and setting the focus of the application manually?
I've had problems in the past with tab ordering getting itself all confused and I've usually just resorted to going through the application from scratch and setting the order myself manually. I realise that this may well not be what you are looking for but I don't know of anything else
