Hi,
you can take the testcase from here:
https://www.grapecity.com/forums/winforms-edition/c1winc1truedbgridc1truedbg_3
The problem we have with C1TDBGrid occurs only with specific system configuration and 3 monitors(2 big monitors and 1 small monitor/Laptop),
- The smaller monitor MUST be in the centre, if it is left/right this problem does not occur.
- The smaller monitor MUST be set as main display, if one of the other monitors is the main display this problem does not occur.
- The smaller monitor MUST have increased scaling. The higher the scaling, the smaller the range of motion. If the scaling is 100%, this problem will not occur.
Monitor resolution: (the smaller monitor must have a smaller resolution)
•Smaller monitor/laptop, middle: 1680x1050.
•2 Big monitors, left/right: 1920x1080
After starting the application you need to move the application window to one of the big monitor and try to change the size of one column in C1TDBGrid.
After changing the size of the column size, you are restricted to move the mouse cursor to a limited area, an invisible border is set for the window.
From the image bellow:
When you have the test app on Monitor 2 you get the invisible border on the left side and bottom.
When you habe the test app on Monitor 3 you get the invisible border on the right side and bottom.
Best,
Jens
