I have given tab index 1, 2, 3, 4, 5,.... so on to all my input controls on the screen. However when I run the screen in preview mode the tab order is top to bottom and left to right irrespective of the tab index. Any idea why this is happening?
The TabIndex does not work in that way. PowerApps really only recommends one of two values for TabIndex - either 0 or -1.
0 means it will participate as a tab stop control. -1 means it will not stop via tab.
PowerApps tabs from top to bottom, left to right in a Z pattern. The X and Y properties of the controls will determine when they are selected by tab.
If you have a control in the top left with a Y property of 2 and a control to the left of it with a Y property of 1, then PowerApps will tab from the second control to the first because it is going from top down and the second control is more "top" then the first.
You can read more about this and other options for grouping controls with the Experimental Enhanced Group Control.
I hope this is helpful for you.
Actually tabbing the controls doesn't even do the "Z" pattern. it seems to randomly jump around to controls in on particular order at all.
If your Tab Indexes are all 0 and there are no groupings of controls on the screen, it will "Z" through it.
If any of the above is not the case, it will seem random.
If you've enabled the container control option in the settings then this will change the behavior of the tab as well (if you use a container)
