I have a grid with approximately 200 records, the grid is read write and the user can enter data in the grid.

in a typical example the user enters data in row no 5 in the grid, he then uses the mouse to scroll to row no 100, he decides to enter in information in row no 100, however when he tries to click on row no 100 , the cursor jumps to row no 5.

basically what i understand is that the visible row and the active row are not synchornised together when the user uses the vertical scroll buttons and the cursor jumps to the active row when the user clicks on the grid.

how do i solve this
