Thank you for your reply.
I'm sorry, I didn't tell you.
Panel1 is autoscroll=true
So you're adding tlp to panel 1 so you're automatically adding tlp rows and trying to scroll from panel 1.
so I think that don’t need monitor 32,000 pixel
And the absence of the image in PictureBox is a simple sample code that I wrote to check the correct position in TLP first before loading the actual image.
The point I asked is why there is a problem with the display of PictureBox from row 108 and above of TLP.
