move button along with picturebox vb/c#

问题

I am working on a mapped DVR/cctv UI.
I made it myself, so I did not use google's API. I just cut off big part of the map where I need it.

so, if I do have a really big map, then it won't fit in my pc's resolution, I haven't found a code to move the picture inside the pictureBox, but what I did is to move the pictureBox inside a panel. then it looked like a map, with boundaries. :)

now, I want to be able to save/attach this button to the picture.. so whenever and wherever I move the pictureBox, button gets along with it. even if goes outside the form, but when I drag it back, it appears to where it was let's say, attached just imagine the button like googlemap's marker. that's what I wanted to happen.

its like I am building my own offline google map..

if you have queries, feel free to ask. TIA

Simply add your button as a child of your picturebox:

button1.Parent = pictureBox1;
//or
pictureBox1.Controls.Add(button1);

Then you can use the Location property of your button to set it accordingly, that location is relative to your pictureBox, not your form.

If you want to keep the design location of your button, you can try this code:

Point loc = pictureBox1.PointToClient(button1.PointToScreen(Point.Empty));
button1.Parent = pictureBox1;
button1.Location = loc;
