Focus on the selected row when scroll


How can I preserve the focus on the selected row when I scroll up or down the DbAdvgrid?
I want to scroll the grid whit the mouse wheel, without change the row that is seleted. 
I use WheelAction:= waScroll and ShowSelection= True


Set grid.PageMode = false.

Not working.

The selected row loses the focus when I sroll up or down the DBAdvGrid.

I cannot reproduce this and see no reason for this. Please do a runtime check that grid.PageMode = false and verify that you do not have grid event handlers that might affect this.
