Hi,
The VScrollBar and HScrollBar objects has a property called SupportsThumbTrack, which has to be set to true to have the GridDataBoundGrid to be updated when the scroll thumb track is moved.
Please refer the sample code below:
gridDataBoundGrid1.VScrollBar.SupportsThumbTrack = true;
gridDataBoundGrid1.HScrollBar.SupportsThumbTrack = true;
And also I have attached a sample in the below location that showcases the behavior:
