object error

I am using a view from a different database to populate my datagrid. Once the user hits import button inside the datagrid the record is removed from view. the screen goes through the motions but doesn't remove the record from view and it gives me this error: Object reference not set to an instance of an object.

private void gridImport_ItemCommand(object source, DataGridCommandEventArgs e)
		{
			if(e.CommandName == "import")
			{			
				string proposal_number=e.CommandArgument.ToString();				
				
				TransferProposalPackage(proposal_number + ".pdf");
				ADTransfer.Transfer transfer = new ADTransfer.Transfer(proposal_number,Cycle.ColumnValue.pk_cycle.ToString());
				lblErrMsg.Text=transfer.errMessage;
				bindDataGrid();
 
						
			}			
 
		}
