Scrolling option is not working after deleting record from a grid. Out of Range Exception Coming..any idea. I am sending code here protected override void OnMouseWheel(MouseEventArgs e) { if ((e.Delta > 0 ) && (this.Binder.CurrentPosition >0) ) { this.Binder.CurrentPosition = this.Binder.CurrentPosition - 1; this.ScrollCellInView(this.Binder.CurrentPosition, 0); } if ((e.Delta < 0 ) && (this.Binder.CurrentPosition < this.Binder.RecordCount-1) ) { this.Binder.CurrentPosition = this.Binder.CurrentPosition + 1; this.ScrollCellInView(this.Binder.CurrentPosition+1, 0); } } Regards shashi

Hi Shashi, You need to change the currentcell position and binder.currentPosition before delete the record from the grid. Here is a code snippet this.gridDataBoundGrid1.Binder.EndEdit(); this.gridDataBoundGrid1.Binder.SuspendBinding() ; int RowIndex = this.gridDataBoundGrid1.CurrentCell.RowIndex; int ColIndex = this.gridDataBoundGrid1.CurrentCell.ColIndex; int Position = this.gridDataBoundGrid1.Binder.CurrentPosition; ArrayList list = this.gridDataBoundGrid1.DataSource as ArrayList; if(list != null ) { this.gridDataBoundGrid1.CurrentCell.MoveTo(0,0); this.gridDataBoundGrid1.Binder.CurrentPosition = 0; list.RemoveAt(list.Count -1 ); } this.gridDataBoundGrid1.Binder.ResumeBinding(); this.gridDataBoundGrid1.Binder.EndEdit(); this.gridDataBoundGrid1.Refresh(); this.gridDataBoundGrid1.Focus(); this.gridDataBoundGrid1.CurrentCell.MoveTo(RowIndex , ColIndex); this.gridDataBoundGrid1.Binder.CurrentPosition = Position; Here is a sample. http://www.syncfusion.com/Support/user/uploads/arraylistsource_3f0b7e16.zip Could you please run this at your end and let me know how it goes? Thanks for choosing Syncfusion Products. Regards, Haneef

if ((e.Delta > 0 ) && (this.Binder.CurrentPosition >0) )
{
this.Binder.CurrentPosition = this.Binder.CurrentPosition - 1;
this.ScrollCellInView(this.Binder.CurrentPosition, 0);
}
if ((e.Delta < 0 ) && (this.Binder.CurrentPosition < this.Binder.RecordCount-1) )


{
this.Binder.CurrentPosition = this.Binder.CurrentPosition + 1;
this.ScrollCellInView(this.Binder.CurrentPosition+1, 0);
}


/////////////

this.Binder.RecordCount returns only root tables recordcount so scroll comes upto that row count but there are around 150 rows.

Is there any solution...

Thanks in Advance...
