When setting the screen readability in Win 7 to more than 100% (125% or 150%), the scrollbars of a grid are not visible anymore. The grid that I'm using has application styling enabled.
Hi,
I doubt this has anything to do with the grid. My guess is that the grid is being resized automatically by the form's AutoScaling and the right and bottom parts of the grid are out of view.
I've seen the same thing happen with any control. It seems to be related to Docking or Anchoring. I've seen it more with Dock than Anchor, personally. Anchor seems to work better.
Try setting different options on the AutoScaleMode of the form. Or try using Anchor instead of Dock (or vice versa).
