Hi!

It is possible to catch the event BEFORE user click reach the scroll bar of grid and lock the screen, then unlock just after scrolling. However, this require a lot of work and I did not really tested if mouse click on the locked form will be able to fire grid scrolling by scrollbar, so think if you really need this. (At least click on the button on locked screen fire button's click event, but I know a lot of differences between locked screen and unlocked related to grid behavior, so I'm not sure here.)

To catch the event before scrolling, you require to put transparent shape over the grid scroll bar. Then, after user click on scrollbar, hide the shape, lock the screen and forward mouse event to the form again. After you unlock the screen, you require to show the transparent shape again. Code sample of how to forward mouse events to the form again by API functions you can find in the Fancy ToolTip control that you can find here in the downloads section. It used the same approach - when user clicks on the tool tip accidentally, tool tip is hidden and any control under tool tip works as required, include ActiveX controls.

When tabbing through grid cells, it is also required to lock the screen in the BeforeRowColChange. It is tricky also because this event called when grid losing focus and grid reconstruction happens. When first you can catch in the LostFocus of the container where grid is placed and unlock screen there, third is hard to avoid, but I guess reconstruction is not used in your grid.

Tremendous...

Let me know if you have any questions.
