why I have an empty Row in the end of my greedview? : I have always an emty row in the end of my grid View 

 gv_remboursement.DataSource = listResult;

 gv_remboursement.VirtualItemCount = iTotal;

 gv_remboursement.DataBind();

 listResultContent.Visible = isVisible;
           

listResult contains the list that I fill from the data base
