To fix truncation in a scrollable Canvas App form and get a clean edge-to-edge look, focus on these three areas:
Mind the Scroll Bar: A vertical scroll bar takes up space. Set your Form’s Width to Parent.Width - 20 to prevent the bar from overlapping your content.
Fix: Set the Form's Width property to Parent.Width - 20 (or whatever the scroll bar width is in your theme). This ensures the form content ends before the scroll bar begins.
Zero Out Padding: Check your Parent Container. Set Padding (Top, Bottom, Left, Right) to 0 so the form can actually reach the screen edges.
Fix: Select your Vertical Container (the one holding the form) and set all Padding properties (Top, Bottom, Left, Right) to 0.
Card Behavior: Ensure Width Fit is turned On for your Data Cards so they snap correctly to the form's boundaries without overflowing.
Select the problematic Data Card and ensure Width fit is turned On. This allows the card to dynamically fill the available row space without overflowing the form's boundary.
