Scrolling versus cell position

I need the position (X and Y coordinates) of the selected cell when scrolling a TAdvStringGrid. Can you give me some advice how to get this information?

Thank you in advance for your support.

grid.CellRect(col,row) returns the coordinates of the cell you specify.

Is there an event available which is triggered when the TAdvStringGrid is scrolling?

The grid.OnTopLeftChanged event is triggered when the grid's scroll position changed.

Thank you 'OnTopLeftChanged' was what I needed.
