DBGRID dragging scroll bars and mouse wheel issues

Scroll bar Drag problem

By default, when you drag, the data in the grid does not change, and then it changes when you release the mouse.

When the method is dragged, the current record is changed without the new control

Mouse wheel problem:

Method 1: Only the lower version of the IDE, such as D7, can scroll down all the time. 2007 and the newer IDE above does not have this problem.

Method 2, the selected record row background does not change, but the current record of the dataset is variable.
